Reaction Steps

To 6.4 g of 3-phenoxy-4-fluorobenzyl bromide was added 7 ml of triethylphosphite, and the mixture was stirred at 140° C. for seven hours. After cooling, 13.1 g of the reaction mixture was purified by column chromatography on silica gel (eluent: benzene) to give 6.3 g of diethyl 3-phenoxy-4-fluorobenzylphosphonate.
