实验步骤: To a 3-necked 3 L RB flask equipped with overhead stirrer, condenser and N2 inlet line was added NaH (Morton Thiokol, Inc.-Alfa Products, 60% in mineral oil, 44 g, 1.1 mol). After washing with hexane (3×200 mL), dry THF (1.1 L) was added to the flask. After cooling to 0°, 2-amino-3-methoxy-2-methyl-1-propanol (61C, 119.16 g, 1.0 mol) was added dropwise to the flask at such a rate that the reaction temperature remained below 30°. The resulting slurry was cooled to 0°. Iodomethane (Aldrich, 141.94 g, 1.0 mol, 62.25 mL) was added dropwise to the mixture at such a rate that the reaction temperature remained below 30°. After the mixture was stirred for 1 h, EtOH (25 mL) was added to quench the reaction. The volume of the reaction was reduced to 200 mL. This material was diluted to 2 L with Et2O, filtered and the solvent removed. Fractional distillation of this material gave 91.02 g (68.3% yield of 1,1-bis-(methoxymethyl)ethylamine, bp 146°-149°, (C,H,N).

The reaction mixture was diluted with ethyl acetate and poured on sat. aq. NH4Cl. The water phase was extracted 3 times with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered and evaporated. The residue was purified by column chromatography (cyclohexane/ethyl acetate 1:1) to give as a yellowish oil 2-(3-Ethynyl-quinolin-6-yloxy)-N-(2-hydroxy-1-methoxymethyl-1-methyl-ethyl)-2-methylsulfanyl-acetamide (200 mg) as a mixture of diastereoisomers.
