Reaction Steps

Ethyl thiooxamate (172 mg) was suspended in ethanol (5 ml) at 0° C., followed by the addition of hydrazine monohydrate (63 μl). While the resulting gas was suctioned, the resulting mixture was stirred for 30 minutes. Ethyl (pyridin-4-yl)glyoxylate hydrate (254 mg) was added to the reaction mixture and the mixture was stirred at room temperature for 30 minutes. After heating under reflux for 4 hours, the reaction mixture was concentrated. The yellow powder thus precipitated was collected by filtration and dried, whereby the title compound (140 mg) was obtained.
