Procedure:
195 a) To a cooled, stirred solution of 2-amino-benzoic acid ethyl ester (10.0 g, 60.5 mmol) in ether (50 mL) at 5° C. was added triethylamine (8.44 mL, 60.5 mmol). methanesulfonyl chloride (4.68 mL, 60.5 mmol) in ethyl acetate (50 mL) was added dropwise to the mixture, was stirred for 1 hour at 5° C. then at room temperature for 18 hours. Water (100 mL) was added to the stirring mixture and was extracted with ethyl acetate (3×50 mL). The combined organic was washed with water (2×50 mL) and saturated aqueous sodium chloride. The organic layer was dried over magnesium sulfate, filtered and evaporated. The residue was stirred with warm methanol (30 mL) for 30 minutes and cooled to room temperature.
