Trichloroisothiazole (4.7 g, 0.025 mol) and a solution of 0.02 mol of n-propyl trifluoromethane sulfonate in CCl4 were heated at 110° and CCl4 was removed via distillation. After heating at 110° for 11/2 hrs, the reaction was cooled and ether added. The ether was cooled in an ice bath and the solid collected to yield 2.1 g (28%) of product, mp 95°-99°. Analysis--Calculated for C7H7Cl3F3NO3S: C, 22.09; H, 1.86; Cl, 27.95; N, 3.68; S, 16.84. Found: C, 2160; H, 1.94; Cl, 27.15; N, 3.57; S, 16.27.
