Acetic acid (0.060 mL) was added to a mixture of (R)-3-[N-[3-(trifluoromethyl)benzoyl]glycyl]aminopyrrolidine (0.050 mL) with 4-butylbenzaldehyde (0.18 mmol), NaBH3CN (0.23 mmol) and methanol (1.85 mL). The resulting reaction mixture was stirred at 60° C. for 12 hours, cooled to room temperature, loaded onto a Varian™ SCX column and washed with methanol (15 mL). The obtained crude product was eluted with a solution of 2 M NH3 in methanol (5 mL) and concentrated to thereby afford (R)-1-(4-butylbenzyl)-3-[[N-(3-trifluoromethylbenzoyl)glycyl]amino]pyrrolidine (Compd. No. 1648) (20.6 mg, 89%). The purity was determined by RPLC/MS (91%). ESI/MS m/e 462.2 (M++H, C25H30F3N3O2).
