Procedure: 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).

Procedure: (3-Ethynyl-quinolin-6-yloxy)-methylsulfanyl-acetic acid (413 mg), 1-hydroxy-7-azabenzotriazole (HOAT) (267 mg), O-(Benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (TBTU) (630 mg), 2-amino-3-methoxy-2-methyl-propan-1-ol (180 mg) and triethylamine (0.75 ml) in dry CH3CN (20 ml) were stirred at ambient temperature overnight. 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.
