By the procedure of Example 1, 7.9 g of chlorosulfonyl isocyanate was reacted with 10 g of 2-(1,2,3-thiadiazol-4-yl)phenol [prepared by the procedure of U.S. Pat. No. 3,940,407] in 125 ml of dry toluene. The reaction mixture was stirred at 25° C. for 1 hour, then heated at 100° to 110° C. for 1 hour. The resulting solution was cooled to 25° C., filtered, and the filtrate was concentrated in vacuo to yield 14 g of the title compound as a crude oil. The IR showed an isocyanate absorption at 2220 cm-1.
