Procedure
2-Phenyl-1,2,5-thiadiazole-3-one (3.1 g., 0.02 mole) was refluxed for 4 minutes in phosphorus oxychloride (20 ml.) and then cooled slowly. Ether (60-100 ml.) was added and the precipitate was filtered in a stream of nitrogen and washed well with anhydrous ether. The precipitate was then triturated with acetonitrile, refiltered and rewashed with acetonitrile and dried in a stream of nitrogen, m.p. (dec.) 110° C.
