Procedure
A mixture of (R)-3-[{N-(2-amino-5-trifluoromethylbenzoyl)glycyl}amino]-1-(4,5-methylenedioxy-2-nitrobenzyl)pyrrolidine (30.5 mg), 10% Pd-activated carbone (6 mg), and methanol (3 mL) was stirred under a hydrogen atmosphere at room temperature for 10 h. The Pd catalyst was filtered off through Celite, and the filtrate was concentrated. Solid phase extraction (Bond Elut™ SI, 20% methanol/AcOEt) afforded (R)-1-(2-amino-4,5-methylenedioxybenzyl)-3-[{N-(2-amino-5-trifluoromethylbenzoyl)glycyl}amino]pyrrolidine (Compound No. 2127) (21.9 mg, 76%): The purity was determined by RPLC/MS (95%); ESI/MS m/e 480.1 (M++H, C22H24F3N5O4).
