Procedure
A solution of 3-(2-chloro-benzenesulfonyl)-cyclopentanecarboxylic acid (0.25 g, 1.0 eq) in DMF (4.0 mL) was treated with DIPEA (0.22 mL, 1.5 eq) and HATU (0.39 g, 1.2 eq). The mixture was stirred at RT for 15 min, then a solution of aminoacetonitrile hydrochloride (0.12 g, 1.5 eq) and DIPEA (0.22 mL, 1.5 eq) in DMF (1 mL) was added. The resulting solution was stirred at RT overnight and then purified by preparative HPLC. The title compound was obtained as a light yellow gum (0.10 g, 37%). MS (ESI): m/z=327.1 [M+H]+.
