Participants

Reaction Steps

5.5 grams (0.02 mole) of 4-(di-3-thienyl-methylene)-N-methyl-piperidine were dissolved in 50 ml of methanol and treated with 7.2 grams of 30% hydrogen peroxide dropwise with ice cooling and left at room temperature for 8 days. Excess hydrogen peroxide was destroyed by the addition of Pt-carbon. After the filtering and removal of the solvent at room temperature the amineoxide was crystallized in ethyl acetate. M.P. 92°-96° C.; Yield: 77%.
