Versuchsvorschrift

To a mixture of 1.74 grams (0.02 mole) of ethyl isothiocyanate and 25 milliliters of benzene was added 2.14 grams (0.02 mole) of benzylamine. The temperature rose from 25° C. to 41° C. The reaction mixture was then refluxed on a steam bath for about 20 minutes to bring the reaction to completion. The mixture was evaporated under vacuum to give 3.67 grams of 1-ethyl-3-benzyl thiourea.
