Procedure

Methylmagnesium bromide (3.0M in diethyl ether, 47 ml) was added dropwise to a solution of 5,6,7,8-tetrahydro-5-oxo-2-(phenylmethoxy)quinoline (29.6 g) and toluene (1l) at 0° C. The reaction mixture was allowed to warm to room temperature, with stirring. The reaction mixture was then quenched with saturated ammonium chloride solution, the layers were separated, and the aqueous phase was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous magnesium sulfate, filtered, and the filtrate was concentrated to provide 31.7 g (92.0%) of product.
