Reaction Steps

To a solution of 7-(3-chlorothiophen-2-yl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one (0.74 g) in ethyl acetate (10 ml) were added pyridine (0.21 g) and sulfuryl chloride (1.1 g) at room temperature, and the mixture was stirred at the same temperature for 3 hours. To the reaction solution was added ethyl acetate, and the mixture was washed with sodium hydrogen carbonate solution, water and saturated brine, dried with magnesium sulfate and concentrated under reduced pressure. The residue was purified with silica gel column chromatography (EtOAc/hexane) to give 7-(3,5-dichlorothiophen-2-yl)-4-methyl-5,6,7,8-tetrahydroquinolin-5-one (0.56 g).
