Sodium Carbonate → 2-[4-(1,3-Benzodioxol-4-Ylmethylamino)-6-Methyl-2-Pyrimidinylthio]Acetamidoxime

Participants

Reaction Steps

A mixture of 6.20 g. (0.02 mole) of (4-methyl-6-piperonylamino-2-pyrimidinylthio)acetonitrile, 2.76 g. (0.04 mole) of hydroxylamine hydrochloride and 8.48 g. (0.08 mole) of sodium carbonate in 100 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 triturated with ether and the insoluble material was collected and recrystallized from a mixture of ethanol-N,N-dimethylacetamide to give 3.5 g. of product, m.p. 190°-192° dec.
