Reaction Steps
Starting from 2-amino-6-chlorobenzenesulfonamide and isopropyl isothiocyanate, and following a procedure analogous to the one described in Example 4a, N-(2-amino-6-chlorobenzenesulfonyl)-N′-isopropylthiourea was prepared; m.p. 144-146° C. Subsequent ring closure with phosgene by a procedure analogous to the one described in Example 4b gave the title compound; m.p. 273-275° C.
