Participants

Reaction Steps

To a solution of (3-(2,6-dimethylbenzyloxy)-4-methoxyphenyl)methanol (Step C, 5.23 g, 20.4 mmol) and CBr4 (10.16 g, 30.6 mmol) in dry CH2Cl2 (20 ml) was added portion wise triphenylphosphine (8.03 g, 30.64 mmol) at 0° C. The reaction mixture was stirred for 1.5 hours, filtered, concentrated and purified by flash chromatography on a silica gel column (hex: ethyl acetate 2:1) to give the title compound.
