反応手順

257 mg (1.1 mmol) of nickel chloride hexahydrate and then 770 mg (20.3 mmol) of sodium borohydride were added to a mixture of 1.00 g (5.0 mmol) of ethyl quinoline-6-carboxylate and 15 ml of methanol under cooling with ice, and they were stirred at room temperature for 20 minutes. Methanol was evaporated, and the residue was purified by the silica gel column chromatography (hexane/ethyl acetate) to obtain the title compound.
