To 20 mL of the acetonitrile solution containing 2,3-dichlorobenzenesulfonyl isocyanate, prepared as described in the previous example, was added 2.5 mL of cyclopentylamine. This mixture was allowed to sit overnight. The solid precipitate was filtered off and triturated with 5 mL of acetonitrile. Filtration and drying afforded 5.0 g of the title compound as an off-white solid, m.p. 202°-207° C.; NMR (DMSO-d6): δ1.1-1.8 (m, 8H), 3.7 (m, 1H), 6.5 (br d, 1H), 7.6 (t, 1H), 7.9 (dd, 1H), 8.0 (dd, 1H), 10.8 (br s, 1H); IR (nujol): 3343, 1660, 1375, 1170 cm-1.
