Participants

Reaction Steps

A mixture of 11.20 g. (0.03 mole) of [4-phenyl-6-(piperonylamino)-2-pyrimidinylthio]acetonitrile, 4.14 g. (0.06 mole) of hydroxylamine hydrochloride and 12.70 g. (0.12 mole) of sodium carbonate in 200 ml of N,N-dimethylformamide was heated on a steam bath for four hours. The mixture was filtered and the filtrate was evaporated in a rotary evaporator. The residue was dissolved in ethyl acetate, diluted with petroleum ether and left at room temperature overnight. The precipitate which formed was collected and recrystallized from a mixture of ethyl acetate-petroleum ether to give 4.8 g. of product, mp. 160°-163°.
