Versuchsvorschrift
Starting from 2-amino-5-tert-butylbenzenesulfonamide and isopropyl isothiocyanate, and following a procedure analogous to the one described in Example 4a, N-(2-amino-5-tert-butylbenzenesulfonyl)-N′-isopropylthiourea was prepared; m.p. 128-130° C. Subsequent ring closure with phosgene by a procedure analogous to the one described in Example 4b gave the title compound; m.p. 290-293° C.
