실험 절차

A solution of 2-(3-Ethynyl-quinolin-6-yloxy)-N-(2-hydroxy-1-methoxymethyl-1-methyl-ethyl)-2-methylsulfanyl-acetamide (200 mg) in dry CH2Cl2 (15 ml) was treated with Dess-Martin periodinane (295 mg). The mixture was stirred at room temperature during 1 h then poured on sat aq NaHCO3. After separation the water phase was washed twice with CH2Cl2 The combined organic phases were washed with brine, dried over sodium sulfate, filtered and evaporated. The crude residue was purified by column chromatography (cyclohexane/ethyl acetate 1:1) to give (3-Ethynyl-quinolin-6-yloxy)-N-(1-methoxymethyl-1-methyl-2-oxo-ethyl)-2-methylsulfanyl-acetamide (120 mg) as yellowish oil as a mixture of diastereoisomers.
