Procedure

880 mg of N-tert-butyloxycarbonyl-1-(hydroxyphenylmethyl)cyclopropanesulfonamide were dissolved in 25 ml of ethyl acetate, and 13.4 ml of a 1 N aqueous hydrochloric acid were added. The reaction solution was heated to 65° C. and the completeness of the conversion was checked with LCMS. After 8 hours, the mixture was neutralized with saturated aqueous sodium carbonate solution, and the organic phase was dried over Na2SO4 and concentrated by rotary evaporation. This gave the product (610 mg) with a molecular weight of 227.3 g/mol (C10H13NO3S); MS (ESI): m/e=210 (M−H2O+H+).
