Procedure

To the 2-pyrrolidin-1-yl-propanoic acid (200 mg, 1.4 mmol) in DMF (10 mL), was added HATU (586 mg, 1.5 mmol), 4-amino-benzoic acid ethyl ester (231 mg, 1.4 mmol) and DIPEA (0.5 mL, 2.8 mmol). The reaction mixture was stirred at room temperature for 16 hours, diluted with water and acetonitrile, purified by preparative HPLC, and lyophilized to give ethyl 4-(2-(pyrrolidin-1-yl)propanamido)benzoate.
