HCID 178527971HCID 178527971, compoundYield 80%

Procedure

The procedure was as described in Example 2, but instead of thiosemicarbazide there were present 83.5 grams of 4-phenylthiosemicarbazide 83.5 grams of 4-phenylthiosemicarbazide. After the cooling and filtering with suction there were isolated 83.6 grams (=80% yield) of 2-phenylamino-5-mercapto-1,3,4-thiadiazole having a melting point of 208° to 210° C.
