Procedure

3,4,5-Trichloro-1,2-phenylenediamine (3.02 g, 14.28 mmol), cyclopropyl isothiocyanate (1.53 g, 15.42 mmol), 1-cyclohexyl-3-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate (8.24 g, 19.45 mmol) and pyridine (55 mL) were used according to general procedure I. The product was recrystallized from 1,4-dioxane to afford 3.29 g (83%) of a white solid. MS (CI): m/z 274. Anal. Calcd for C10H8Cl3N3-(0.6 C4H8O2): C, 45.21; H, 3.92; N, 12.76. Found: C, 45.37; H, 3.91; N, 12.76.
