To a solution containing 1-amino-2-(2-fluorobenzoyl)pyrrole (25.8 g, 0.126 mol) and N-(tert-butoxycarbonyl)glycine (22.4 g, 0.128 mol) in 300 ml of dichloromethane was added dicyclohexylcarbodiimide (26.4 g, 0.128 mmol) in two portions over 3 minutes. The reaction mixture was stirred at ambient temperature for 2 hours and then filtered. The filtrate was evaporated to an oil which was purified by HPLC (silica gel, 4:3 hexane-ethyl acetate) to give 37.2 g (82%) of crystals, m.p. 114°-116°.
