Reaction Steps

A solution of (R)—N-(2-(3-hydroxybutyl)-3-(methoxymethoxy)phenyl)acetamide (4.0 g, 14.96 mmol) in acetonitrile (40 mL) was treated with triethylamine (3.13 mL, 22.44 mmol) and cooled to 0° C. Methanesulfonyl chloride (1.46 mL, 18.7 mmol) was slowly added and a precipitate formed immediately. The slurry was stirred at 0° C. After 3 h, the reaction mixture was diluted with ethyl acetate and poured into 5% aqueous sodium chloride solution (50 mL). The layers were separated, and the organic layer washed with additional 5% aqueous sodium chloride solution (40 mL). The combined aqueous layers were extracted with ethyl acetate, and the combined organic layers were concentrated under reduced pressure. The residue was dissolved in toluene (50-75 mL), which was then removed under reduced pressure to afford (R)-4-(2-acetamido-6-(methoxymethoxy)phenyl)butan-2-yl methanesulfonate (5.17 g, 100%) as an amber syrup. The crude was used without further purification. MS (ESI, pos. ion) m/z 250 [M−95].+.
