Reaction Steps
To a solution of {2-[3-(4-ethoxybenzyl)-4-hydroxyphenyl]-2-oxoethyl}phosphonic acid diethylester (1.00 g) in dichloromethane (4.7 mL) was added bromotrimethylsilane (1.6 mL) at 0° C., and the reaction mixture was stirred for 9 hr at room temperature. Methanol (4.0 mL) was added to the reaction mixture, and the mixture was stirred for 10 min at room temperature. Evaporation and crystallization from ethyl acetate-n-hexane gave the title compound (0.72 g) as a pale brown crystal.
