실험 절차
5′-tert-Butoxycarbonylamino-2′-methyl-biphenyl-4-carboxylic acid ethyl ester (6.6 g) was stirred in ethanol (120 ml) and 6M HCl (50 ml) at 20 C for 2 days. The ethanol was evaporated and the residue basified and then extracted with dichloromethane. The dried extracts were evaporated giving the title compound as a pale brown crystalline solid (4 g).
