Potassium Carbonate → n-(3-((2-Chlorothiazol-5-yl)methyl)-5-methyl-1,3,5-oxadiazinan-4-ylidene)nitramide

Participants

Reaction Steps

A mixture of 1.62 g of 3-methyl-4-nitroimino-perhydro-1,3,5-oxadiazine, 2.44 g of 2-chloro-5-chloromethyl-thiazole, 4.2 g of potassium carbonate and 25 ml of N,N-dimethylformamide is heated for 5 h at 60° and then filtered. The filtrate is evaporated in vacuo on a rotary evaporator, and the residue is purified by chromatography [silica gel; dichloromethane/methanol (95:5)]. This gives the title compound, which melts at 132-134°, in a yield of 67%.
