Procedure

A mixture of 144 g of potassium S-p-chlorobenzyl-N-cyano-dithioimidocarbonate, 48 ml of 30% hydrogen peroxide and 1000ml of water was heated to 65° C, returned to room temperature and filtered. The filtrate was acidified with 40 ml of concentrated hydrochloric acid and was filtered. The recovered crystals were washed with water and dried to obtain 90 g of 3-hydroxy-5-(p-chlorobenzylthio)-1,2,4-thiadiazole melting at 138° C.
