実験手順

A suspension of methyl 4-({[(benzyloxy)carbonyl]amino}sulfonyl)benzoate (3.38 g) and 85% pottasium hydroxide (1.28 g) in methanol (40 mL) was stirred for 35 minutes. Methanol was evaporated off, and to the mixture was added 1N hydrochloric acid (20 mL). A white crystal was formed, which was collected by filtration and washed with water and diisopropyl ether, and dried under vacuum. 4-({[(Benzyloxy)carbonyl]amino}sulfonyl)benzoic acid was obtained as a white crystal (2.92 g).
