PROCEDURE

实验过程

A mixture of 5′-amino-2′-chloro-biphenyl-4-carboxylic acid ethyl ester (800 mg), (R) —N-Boc-2-pyrrolidinecarboxylic acid (608 mg) and HBTU (1.46 g) in dry DMF (30 ml) containing N-methylmorpholine (1.26 ml) was stirred at room temp for 18 h. Silica gel (5 g) was then added and the mixture evaporated. The residue was purified by chromatography. Elution with 12:1 petrol:ethyl acetate gave a viscous brown gum (987 mg)
