실험 절차

(S)-3-amino-3-(4-chlorophenyl)propan-1-ol (Intermediate 47) (1.09 g, 5.87 mmol) was added in one portion to 1-(tert-butoxycarbonyl)-4-(tert-butoxycarbonylamino)piperidine-4-carboxylic acid (Intermediate 70) (2.022 g, 5.87 mmol) and DIPEA (3.08 mL, 17.61 mmol) in DMA (20 mL). O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (2.456 g, 6.46 mmol) was added and the resulting solution was stirred at 20° C. for 24 hours. The reaction mixture was evaporated to dryness then diluted with EtOAc (300 mL), and washed sequentially with water (50 mL) and saturated brine (50 mL). The organic layer was dried over MgSO4, filtered and evaporated then triturated with diethyl ether to afford crude (S)-tert-butyl 4-(tert-butoxycarbonylamino)-4-(1-(4-chlorophenyl)-3-hydroxypropylcarbamoyl)piperidine-1-carboxylate (4.66 g, 155%) as a white solid.
