실험 절차

A solution of tert-butyl 4-(3-chlorophenyl)-4-(3-(pyrrolidin-1-yl)propyl)piperidine-1-carboxylate (0.15 g, 0.37 mmol) in dichloromethane (3 ml) was Boc-deprotected using standard reaction conditions (see step (vi)/example 25; TFA (3-13 eq.)) and added dropwise to a solution containing 2-(2-(2-chloro-N-cyclopropyl-6-methylphenylsulfonamido)ethoxy)acetic acid [carboxylic acid 2] (1 eq.), EDCI (1.5 eq.), HOBt (1 eq.) and DIPEA (6 eq.) in dichloromethane (5 ml) at 0° C. The resulting mixture was then stirred at room temperature for 16 h. The reaction mixture was diluted with dichloromethane and washed with aq. ammonium chloride, aq. sodium hydrogen carbonate and water respectively. The organic layer was dried over sodium sulfate, concentrated in vacuo and the crude product purified by chromatography (silica). Yield: 25%
