実験手順: 8-Bromo-1-octanol (25 g, 119.6 mmol) in acetonitrile (50 mL) was added to a stirred solution of N-benzyl-N-methylamine (43.49 g, 358.9 mmol) and potassium carbonate (49.52 g, 358.9 mmol) in acetonitrile (250 mL) at 35° C. The reaction mixture was then stirred at 35° C. for 7 h and then cooled to ambient temperature. The potassium carbonate was filtered and the filtrate was concentrated under reduced pressure. The crude residue was dissolved in MTBE (400 mL) and the organic phase was washed with water, brine and dried over magnesium sulfate. N-methyl-2-pyrrolidone was added and the mixture was concentrated under reduced pressure to remove excess N-benzyl-N-methylamine. MTBE (400 mL) was added and the organic phase was washed with water, brine, and dried over magnesium sulfate, filtered and concentrated under reduced pressure to afford the title intermediate as an oil (˜100% conversion). cooled to ambient temperature The potassium carbonate was filtered the filtrate was concentrated under reduced pressure The crude residue was dissolved in MTBE (400 mL) the organic phase was washed with water, brine dried over magnesium sulfate N-methyl-2-pyrrolidone was added the mixture was concentrated under reduced pressure to remove excess N-benzyl-N-methylamine MTBE (400 mL) was added the organic phase was washed with water, brine dried over magnesium sulfate filtered concentrated under reduced pressure

実験手順: The same procedure as in the synthesis (a) of Example 2 was repeated except that 34.7 g of 8-bromo-1-octanol were used instead of 30 g of 6-bromo-1-hexanol to give 34.1 g (Y., 78%) of 8-acryloyloxy-1-bromooctane. GC; 97%
