Reaction Conditions

Reaction Steps

A mixture of 4-chlorothiazole-5-carbaldehyde (0.15 g), benzenesulfinic acid sodium salt (0.25 g) and dimethyl sulfoxide (7.0 mL) was stirred at 100° C. for 30 minutes. The mixture was cooled to room temperature, poured onto ice/water (50 mL) and extracted with ethyl acetate. The combined organic extract was washed with saturated aqueous sodium chloride solution and dried over magnesium sulfate. The solvent was removed under reduced pressure to afford the title compound as a tan oil (0.23 g).
