실험 절차

To a stirring solution of 4-amino-benzoic acid methyl ester (0.594 g, 3.93 mmol) in a mixture of dichloromethane (15 mL)/pyridine (15 mL) is added 4-methanesulfonyl benzenesulfonyl chloride (1.0 g, 3.93 mmol) and the mixture is allowed to react for 6 h at ambient temperature. The reaction is diluted with ethyl acetate and washed with 1N HCl. The organic layer is separated and dried over sodium sulfate, filtered, and concentrated to give 1.26 g (87%) of the title compound. MS (ES−) (m/e) 368.0 (M−1)−.
