A mixture of {5-[4-(2-cyano-phenyl)-piperazine-1-carbonyl]-pyrrolidin-3-yl}-(2,4-difluoro-benzyl)-carbamic acid 2,2,2-trichloro-ethyl ester (0.078 g, 0.13 mmol), 2,3-difluorobenzaldehyde and acetic acid (cat.) in DCM (5 ml) was stirred for 20 min, and then NaBH(OAc)3 (0.041 g, 0.13 mmol) was carefully added. The reaction mixture was stirred overnight, and was concentrated to give crude product which was directly used for next step.
