3,4-Diethoxybenzene-1-carbothioamide → HCID 19041124, compound

Participants

Reaction Steps

0.7 g of 3,4-diethoxythiobenzamide and 20 ml of ethanol were added to 0.77 g of 2-ethoxycarbonyl-3-hydroxy-6-(2-bromoacetyl)pyridine. The mixture was refluxed for 3 hours. Ethanol was removed by distillation. To the residue was added ethyl acetate-dichloromethane to give rise to crystallization to obtain 0.62 g of 2-(3,4-diethoxyphenyl)-4-(5-hydroxy-6-ethoxycarbonyl-2-pyridyl)thiazole.
