Reaction Steps

A mixture of (R)-3-[{N-(2-amino-5-(trifluoromethyl)benzoyl)glycyl}amino]pyrrolidine (0.050 mmol), 4-vinylbenzyl chloride (9.9 mg, 0.065 mmol), peperidinomethylpolystyrene (60 mg), acetonitrile (1.0 mL) and chloroform (0.30 mL) was stirred at 50° C. for 12 h. The reaction mixture was cooled, loaded onto Varian™ SCX column and washed with CH3OH (15 mL). Product was eluted using 2 N NH3 in CH3OH (5 mL) and concentrated to afford (R)-3-[{N-(2-amino-5-(trifluoromethyl)benzoyl)glycyl}amino-]-(4-vinylbenzyl)pyrrolidine (compound No. 1701) (19.6 mg, 88%): The purity was determined by RPLC/MS (92%); ESI/MS m/e 547.2 (M++H, C23H25ClF3N4O2).
