Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 4-chlorophenylisothiocyanate (17.0 g, 0.10 mole) and methylhydrazine (5.0 g, 0.11 mole) in 80 ml of ethanol was stirred at room temperature for two hours. The reaction mixture was filtered to collect colorless crystalline N-(4-chlorophenyl)-1-methylhydrazinecarbothioamide (18.4 g, mp 152°-154° C.). The reaction mixture was filtered to collect colorless crystalline N-(4-chlorophenyl)-1-methylhydrazinecarbothioamide (18.4 g, mp 152°-154° C.)
