実験手順

To a solution of 1.37 g of 3-aminobenzoic acid and 0.4 g of sodium hydroxide in 50 ml of water, 1.41 g of benzoyl chloride and a solution containing 0.4 g of sodium hydroxide in 5 ml of water were simultaneously added dropwise, in an ice bath, and the mixture was stirred at room temperature for 6 hours. The reaction solution was adjusted to pH 1 by addition of 1N hydrochloric acid, and thus obtained solid was collected by filtration to give 1.92 g (yield 80%) of the title compound as a white solid.
