Dicyclohexylcarbodiimide → HCID 13457756, compound

Participants

Reaction Steps

1-Amino-2-(2-chlorobenzoyl)pyrrole (24.3 g, 0.12 mol) and t-butoxycarbonyl glycine (22.7 g, 0.13 mol) were dissolved in 300 ml of dichloromethane. Dicyclohexylcarbodiimide (26.8 g, 0.13 mol) was added over 3 minutes and the reaction mixture stirred at ambient temperature for 4 hours. The resultant slurry was filtered, and the filtrate evaporated to give 65 g of oil. This oil was purified by flash chromatography (silica, 2:1 hexane-ethyl acetate) to give 21.9 g (48%) of crystals, m.p. 156°-158°.
