41% | With sodium hydroxide; In methanol; dichloromethane; | EXAMPLE 14 3-Morpholin-4-yl-methyl-benzoic Acid Commercially available methyl 3-bromomethyl benzoate (5 g, 22 mmole) was dissolved in dichloromethane (20 mL) and morpholine (3.93 mL, 45 mmol) was added. The solution was allowed to stir for 12 h, and filtered. The solvent of the filtrate was removed under reduced pressure. The resulting crude ester was dissolved in methanol, and sodium hydroxide (4.6 mL of 5N solution) was added. The solution was stirred overnight at 40 C. for 12 h. The solvent was partially removed under reduced pressure. The crude was acidified, dichloromethane was added and the solution was cooled in ice. After one hour, it was filtered, to provide the title product (2.3 g, 41%) as the white solid hydrochloride salt: 1H-NMR (DMSO-d6) delta13.1 (bs, 1H), 11.8 (bs, 1H), 8.14 (s, 1H), 7.92 (m, 2H), 7.65 (t, J=4 Hz, 1H), 4.39 (bs, 2H), 3.91(m, 4H), 3.12 (m, 4H). MS (EI-NEG):[M+]221; Anal.RP-HPLC: 99% purity. |

45% | In trichlorophosphate; at 160.0℃; for 0.333333h;Microwave irradiation; | General Method DPOCl3 2 mL (solvent) was added to a mixture of the diamine Dl (1.0 equiv.), the carboxylic acid D2 (1.1 equiv.) and the reaction mixture was heated in a microwave reactor at +160 0C for 20 minutes. The product mixture was mixed with ice/water mixture. The products were collected by filtration, or by extraction with CH2Cl2. Purification by preparative HPLC, afforded each product as a base. The base was dissolved in CH2Cl2MeOH (9:1) and hydrochloric acid (IM HCl in diethyl ether) was added until precipitation formed. The solid hydrochloride salt was collected by filtration and dried.; Example 55; 7-(4-Methoxyphenyl)-2-[3-(morpholin-4-ylmethyl)phenyl]-3J?-imidazo[4,5-6]pyridine hydrochloride EPO <DP n="104"/>The title compound was prepared in accordance with the general method D using 4-(4- methoxyphenyl)pyridine-2,3-diamine (obtained from Example l(c)) (50 mg, 0.232 mmol) and 3-mophiholin-4-yhnethyl-benzoic acid (56 mg, 0.255 mmol), affording 0.041 g (45%) of the title compound.1H NMR (OMSO-d6) delta ppm; 11.21 (s, 1 H), 8.49 - 8.53 (m, 1 H), 8.44 (d, 1 H), 8.36 (d, 1 H), 8.29 (d, 2 H), 7.86 (d, 1 H), 7.70 (t, 1 H), 7.59 (d, 1 H), 7.17 (d, 3 H), 4.47 (s, 2 H), 3.92 - 4.01 (m, 2 H), 3.88 (s, 3 H), 3.79 (d, 2 H), 3.26 - 3.34 (m, 2 H), 3.09 - 3.21 (m, 2 H); MS (AP) m/z 401 (M+l). |

100% | With methanol; sodium hydroxide; at 50.0℃; for 16.0h; | To a solution of methyl 3-(mo holinomethyl)benzoate (5.02 g, 21.0 mmol) in MeOH (100 mL) was added sodium hydroxide (21.0 mL, 42.0 mmol, 2 M). The mixture was heated at 50 C for 16 h. The solvent was removed, residue was adjusted to pH=3 with 1M HC1, and the suspension was filtered. The solid was dissolved in ACN (15 mL) and concentrated to give 3-(morpholinomethyl)benzoic acid (4.6 g, 100%) as a white solid used without further purification in the next step. |
