Reaction Steps

A catalytic amount of 5% Pd-C was added to a solution of 250 mg of 2-(3,4-diethoxyphenyl)-4-(3-carboxy-4-hydroxy-5-allylphenyl)thiazole in 10 ml of methanol. The mixture was stirred in a hydrogen atmosphere at room temperature for 6 hours. After the completion of a reaction, the reaction mixture was filtered. The filtrate was concentrated. The residue was recrystallized from ethanol to obtain 193 mg of 2-(3,4-diethoxyphenyl)-4-(3-carboxy-4-hydroxy-5-propylphenyl)thiazole.
