Reaction Steps

A mixture of 6.0 g of 2,2-dimethyl-1,3-dioxane-4,6dione and 30 ml of ethyl orthoformate is refluxed on an oil bath for 2 hours, mixed with 8.0 g of 2-amino-3-dimethylthiocarbamoyloxypyridine and again refluxed for 2 hours under stirring. After cooling, the precipitated crystal is filtered and washed with ether to give 6.4 g of 2-(2,2-dimethyl-4,6-dioxo-1,3-dioxan-5-ylidenemethyl)amino-3-dimethylthiocarbamoyloxypyridine. The product is recrystallized from ethyl acetate.
