실험 절차
Trifluoroacetic acid (20 ml) was added to a solution of 4-tert-butoxycarbonylmethoxy-3-methyl-benzoic acid methyl ester from Example E41.1 (3.8 g, 13.6 mmol) in di-chloromethane (40 ml) and the mixture was stirred for 1 h at room temperature. Volatiles were removed in vacuo and azeotroped with dichloromethane to yield the title compound (3.04 g, 100%).
