Reaction Conditions

Reaction Steps

To a solution of 5-phenylbenzo[b]thiophene (1.05 g, 5.0 mmol, 1 eq) in DCM (100 mL) at 0° C. was added ethyl 4-chloro-4-oxobutanoate (0.9 g, 21.4 mmol). The resulting mixture was stirred at 0° C. for 30 minutes. SnCl4 (2.3 mL, 6.0 mmol, 1.2 eq) was added and the mixture was stirred at room temperature overnight. The reaction mixture was quenched with aqueous HCl solution (50 mL, 3 M) and extracted with diethyl ether. The combined organic layers were dried over Na2SO4. After filtration and concentration, the crude product was purified by column chromatography to give the title compound.
