YieldReaction ConditionsOperation in experiment
Intermediate 21 : 2-Methyl-1-(phenylmethyl) 1,2-piperazinedicarboxylate. 2-Methyl 1-(phenylmethyl) 1 ,2-piperazinedicarboxylate was prepared from the corresponding TFA salt (whose preparation is already known in literature eg. in Journal of Medicinal Chemistry (1990), 33(10), 2916-24 or Tetrahedron Letters (1989), 30(39), 5193-6.) To a DCM solution (5ml) of (4-(1,1 -dimethylethyl) 2-methyl 1-(phenylmethyl) 1 ,2,4-piperazinetricarboxylate (500mg) was added, at 00C, TFA (3ml) and the reaction temperature allowed to slowly reach 200C. After complete conversion of the starting material DCM was evaporated, the crude was dissolved in water and extracted with Et2O; then the water phase was basified (pH>9) with solid NaOH and extracted with DCM, the organic layer dried over Na2SO4 and the solvent evaporated to give a colourless oil (92 mg);UPLC RT=0.47; m/z (ES): 279.1 [M+H]+; H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.29 - 7.45 (m, 5 H) 5.09 - 5.25 (m, 2 H) 4.60 - 4.83 (m, 2 H) 3.85 - 4.05 (m, 1 H) 3.69 - 3.84 (m, 3 H) 3.44 - 3.63 (m, 1 H) 2.87 - 3.33 (m, 3 H) 2.65 - 2.84 (m, 1 H).

Intermediate 38: 2-Methyl 1-(phenylmethyl) 4-(5',11 '-dihydrospiro[cvclopentane-1 ,10'- dibenzo[a,d]cvclohepten]-3-yl)-1,2-piperazinedicarboxylate. To a solution of (+) 5',11 '-dihydro-3H-spiro[cyclopentane-1 ,10'-dibenzo[a,d]cyclohepten]- 3-one (Intermediate 7, 60 mg, 0.229 mmol) and 2-methyl 1-(phenylmethyl) 1 ,2- piperazinedicarboxylate (Intermediate 21 , 76 mg, 0.274 mmol) in DCE (4 ml) under nitrogen was added AcOH (0.026 ml, 0.457 mmol). The reaction was stirred at room temperature for 1 h and then NaBH(OAc)3 (72.7 mg, 0.343 mmol) was added and the resulting mixture was stirred overnight. The mixture was diluted with DCM. Organic phase was washed with NaHCOβ sat. sol., brine and concentrated under vacuum. The crude mixture was purified through SiO2 (redisep Catridge 12 g) using cyclohexane: EtOAc (From 100 : 00 to 80 : 20 for 25 min and 80 : 20 for 40 min) to afford title compound (106 mg, 0.202 mmol) as a mixture of two diastereoisomeric racemates.For the major diastereoisomer: 1H NMR (400 MHz, CHLOROFORM-c/) d ppm 7.43-6.98 (m, 8 H); 5.26-5.13 (m, 2 H); 4.61-4.88 (m, 1 H); 4.24-4.01 (m, 2 H); 3.84-3.62 (m, 3 H); 3.48-2.74 (m, 7 H); 2.32-1.75 (m, 10 H); 1.45 (s, 3 H).

YieldReaction ConditionsOperation in experiment
420 mg With (2-dicyclohexylphosphino-2’,4’,6’-triisopropyl-1,1 ‘-biphenyl)[2-(2’-amino-1,1‘-biphenyl)]palladium(II) methanesulfonate; caesium carbonate; In 1,4-dioxane; at 100℃; for 12.0h;Inert atmosphere; To a solution of ferf-butyl 5-bromoisoindoline-2-carboxylate (compound 15a, 1.12 g, 3.75 mmol) in l,4-dioxane (10 mL) was added Ol-benzyl 02-methyl piperazine- l,2-dicarboxylate (CAS: 126937-43-7, Vendor: BePharm, 950 mg, 3.41 mmol), CS2CO3 (1.67 g, 5.12 mmol) and XPhos Pd G3 (289 mg, 0.34 mmol). The mixture was stirred at 100 C under N2 for 12 hrs. After being cooled down, the mixture was filtered and concentrated. The residue was diluted with EtOAc (10 mL) and washed with water (3 mL) and brine (3 mL), dried over anhydrous Na2S04, concentrated to give a cmde product which was purified by flash column (PE/EtOAc = 3/1) to give compound 15b (420 mg) as a yellow oil. MS: calc’d 496 (MH+), measured 496 (MH+).
