Procedure

2.76 g (20 mmol) of thioisonicotinamide and 3.6 g (22 mmol) of ethyl 2-chloroacetacetate were heated under reflux in 30 ml of ethanol for 20 hours. After the treatment with ethyl acetate as the extraction solvent in an ordinary manner, the obtained crude product was purified by the silica gel column chromatography to obtain the title compound.
