Reaction Steps

A solution of 3-butyryl-4-(2-methylphenylamino)quinoline-8-carbaldehyde (2.0 g, 6 mmol) in dichloromethane (100 ml) was stirred at 0°-5° C. and treated with a solution of methylmagnesium iodide in ether until T.L.C. (2% methanol in dichloromethane) showed that mostly new product had formed. The mixture was washed with ammonium chloride solution, dried and evaporated. Chromatography (silica gel, 0.5% methanol in dichloromethane) afforded the required 3-butyryl-4-(2-methylphenylamino)-8-(1-hydroxyethyl)quinoline (0.28 g) as yellow crystals, m.p. 140°-2° C.
