Reaction Steps

2-Phenylethyl isothiocyanate (0.36 g) was added to a stirred slurry of 2-amino-5-chlorobenzenesulfonamide sodium salt (0.50 g) in 5 ml of acetonitrile at 60° C. After 2½ h an additional amount of 2-phenylethyl isothiocyanate (0.18 g) was added, and the temperature was raised to 90° C. for 1½ h. The reaction mixture was treated with 1 ml of 4M acetic acid, 5 ml of ethanol and 0.1 g of charcoal and filtered through celite. The solvent was evaporated and the residue extracted with 10 ml of ethyl acetate. The solvent was evaporated and the oily residue was purified on a silica column eluted with ethyl acetate. The title compound was obtained as white crystals; m.p. 250-252° C.
