Reaction Steps

To a stirred solution of 3-methyl-4-oxo-4,5,6,7-tetrahydrobenzothiophene (500 mg, 3.01 mmol) in CH2Cl2 (15 mL) was added NBS (536 mg, 3.01 mmol) at room temperature, and the mixture stirred for 3 hours at room temperature. The reaction mixture was poured into water (50 mL) and the whole was extracted with diethyl ether (100 mL). The organic layer was washed with water (100 mL×2), brine, dried over MgSO4, and concentrated in vacuo to provide the title product (686 mg, 93% yield).
