YieldReaction ConditionsOperation in experiment
A library of compounds in which R4 was various groups having the formula [CONHR ?] was prepared by the process described above using 4-fluoro-3-nitrobenzoic acid, as follows: [72] Aldehyde resin was mixed with a primary amine (R17-NH2) in [DICHLOROETHANE] (DCE), triethylorthoformate (TEOF), and DMF (containing [1%] acetic acid) in a 1: 1: 1 ratio. After shaken overnight, sodium triacetoxyborohydride (20 eq. ) dissolved in DMF was added (Abdel-Magid, A. F. , et al., Tetrahedron Lett, 3 1: 5595-5598 (1990) ). After the mixture was shaken at room temperature overnight, the resin was filtered and washed with DMF (3 x 5 mL), [MEOH] [(3 X 5] mL), DMF [(3 X 5] mL), [MEOH] [(3 X 5] mL), and [CH2CL2] [(3 X 5] mL). The resin was washed twice with 5 mL DMF containing [1%] Hunig's base. To the filtered resin was added a mixture of 4-fluoro-3-nitrobenzoic acid (FNBA, 10 eq. ) and diisopropylcarbodiimide (DIC, 5 eq. ) in 2: 1 DMF : DCM. After shaking at room temperature overnight, the resin was filtered and washed with DMF (3 x 5 mL) and [CH2C12] (3 x 5 mL). [73] The resin was shaken with a primary amine [(R2-NH2)] in DMF for 8 hrs, filtered, and washed with DMF (6 x 5 mL), [MEOH] [(3 X 5] mL), and CH2C12 (3 x 5 mL). The aryl nitro group was reduced by the addition of tin (II) chloride dihydrate (20 eq. , >2 M) and N-methyl morpholine (NMM, 20 eq. ) in N-methyl pyrrolidinone (NMP). After shaken at room temperature overnight, the resin was filtered and washed with NMP (3 x 5 mL), [MEOH] (3 x 5 mL), and [CH2CI2 (3 X 5] mL). The resulting resin was shaken at room temperature with cyanogen bromide (5 eq. ) overnight, filtered, and washed with CH2Cl2 (3 x 5 mL), [MEOH] (3 x 5 mL), and CH2CI2 (3 x 5 mL). To produce a free amine, the resin was shaken for 30 min. in CHCl2 with the addition of sodium methoxide in methanol, filtered, and washed with CH2Cl2 [(4 X 5] mL). [[74]] In the final diversification step, the resin was heated at 500 C in DMF with a mono- substituted epoxide [[RLCH (-CH2O-)].] After shaking for 2 to 4 days the resin was filtered and washed with DMF (5 x 5 mL), [MEOH] [(3 X 5] mL), and CH2Cl2 (3 x 5 mL). T he resin-bound benzimidazole was cleaved from the solid-support by treatment with TFA: [CH2C12] (2: 3) for 1 hour at room temperature.

45% General procedure: To solutions of the corresponding 2-phenoxyalkylcarboxylicacids in DMF (5 mL/mmol) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI; 1.1 equiv) and 1-hydroxy-7-azabenzotriazole (1.1 equiv). The solutions were stirredat room temperature for 30 min, then the corresponding benzylamines(1.2 equiv) and diisopropylethylamine (3.0 equiv) wereadded. The resulting mixtures were stirred at room temperaturefor an additional 16 h, then poured into 10% aqueous citric acidsolutions. The aqueous mixtures were extracted with EtOAc, andthe extracts were washed with 5% aqueous NaHCO3 and brine, thendried over MgSO4, filtered, and evaporated to provide white solids.The solids were crystallized from EtOAc/hexane to provide theproducts 1, 2, and 6a.

The solution was stirred at room temperature for 30 minutes. Diisopropylethylamine (0.28 mL, 1.7 mmol, 3.0 eq) was then added, and the solution was stirred at room temperature for 16 hours. The reaction was poured into 10% aqueous citric acid (20 mL) and extracted with EtOAc (30 mL x 3). The combined organic extracts were dried over Na2SO4, and evaporated to provide a residue which was subjected to chromatography on silica gel with 20% EtOAc/hexane. The fractions were pooled and evaporated to yield 91 mg (45%) of compound 11a (designated MBX 1684) as a white solid: Rf 0.52 (50% EtOAc-Hexanes); mp 136-138 C; MS (ESI) m/z 368.0 [M+H]+; 1H NMR (CDCl3) delta 7.37 (d, IH), 7.19 (dd, IH), 6.91 (s, IH), 6.85 (d, IH), 6.76-6.68 (m, 3H), 5.95 (s, 2H), 4.73 (q, IH), 4.39 (m, 2H), 1.64 (d, 3H).
