To a solution of 2-(3-ethynyl-8-methyl-quinolin-6-yloxy)-N-(2-hydroxy-1-methoxymethyl-1-methyl-ethyl)-2-methylsulfanyl-acetamide (120 mg) in dry THF (7 ml) NaH (19 mg, 60% in oil) was added at room temperature under a nitrogen atmosphere. After 30 minute iodomethane (30 □l) was added to the reaction mixture. After stirring during 5 h one equivalent of NaH and one equivalent of iodomethane were added. The mixture was stirred overnight at room temperature, then quenched with water and diluted with ethyl acetate. The water phase was extracted twice with ethyl acetate and the combined organic phases dried over sodium sulfate, filtered and evaporated. The crude residue was purified by column chromatography (cyclohexane/ethyl acetate/dichloromethane, 1:1:1) to give 2-(3-ethynyl-8-methyl-quinolin-6-yloxy)-N-(2-methoxy-1-methoxymethyl-1-methyl-ethyl)-2-methylsulfanyl-acetamide (46 mg) as a light brown oil.
