Reaction Steps

Starting from 2-amino-4-(benzenesulfonyl)benzenesulfonamide and isopropyl isothiocyanate, and following a procedure analogous to the one described in Example 4a, N-(2-amino-4-(benzenesulfonyl)benzenesulfonyl)-N′-isopropylthiourea was prepared; m.p. 178-180° C. Subsequent ring closure with phosgene by a procedure analogous to the one described in Example 4b gave the title compound, m.p. 308-310° C.
