Procedure

Ammonia was passed at -30° C. into a solution of 130.3 g of 2-chlorosulfonylphenyl methanesulfonate in 1 l of tetrahydrofuran, and the conversion was checked by thin-layer chromatography. After the reaction was complete, the tetrahydrofuran was distilled off under reduced pressure from a water pump and the residue was triturated with water and diethyl ether. This gave 110.2 g (91%) of the title compound of melting point 131°-132° C.
