A mixture of (1-diazo-2-oxo-propyl)-phosphonic acid dimethyl ester (Bestmann's reagent) (43 mg) and 2-(3-ethynyl-quinolin-6-yloxy)-N-(1-methoxymethyl-1-methyl-2-oxo-ethyl)-2-methylsulfanyl-acetamide (60 mg) in MeOH (6 ml) was cooled to 0° C. Solid K2CO3 (40 mg) was added and the mixture stirred during 16 hour allowing the temperature raising to 25° C. The reaction mixture was diluted with ethyl acetate and poured onto brine. 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 to give 2-(3-ethynyl-quinolin-6-yloxy)-N-(1-methoxymethyl-1-methyl-prop-2-ynyl)-2-methylsulfanyl-acetamide (52 mg) as a light brown oil as a mixture of diastereoisomers.
