Procedure

A solution of 1 g of 2-(3,4-diethoxyphenyl)-4-(4-allyloxy-3-methoxycarbonylphenyl)thiazole in 25 ml of o-dichlorobenzene was refluxed for 15 hours with heating. After the completion of a reaction, the solvent was removed by distillation. The residue was recrystallized from diisopropyl ether to obtain 1 g of 2-(3,4-diethoxyphenyl)-4-(3-methoxycarbonyl-4-hydroxy-5-allylphenyl)thiazole.
