Reaction Steps

A mixture of 4-fluorobenzyl bromide (4.86 g, 0.026M) and trimethylphosphite (10 mL, 0.085M) is heated at the reflux temperature for 48 hours. The solution is cooled and excess trimethylphosphite is removed under reduced pressure. The crude product is chromatographed over silica gel (40-63 mμ, 400 g, 45 mL fractions, ethyl acetate), eluting with ethyl acetate. Fractions 41-80 are combined, concentrated, and placed under vacuum for 36 hours. The product (4.52 g) is a colorless oil.
