Procedure
Starting from 2-amino-4,5-difluorobenzenesulfonamide and ethyl isothiocyanate, and following a procedure analogous to the one described in Example 4a, N-(2-amino-4,5-difluorobenzenesulfonyl)-N′-ethylthiourea was prepared. The crude compound was used without further purification in a cyclisation step analogous to the one described in Example 4b to give the title compound; m.p. 246-252° C.
