Reaction Steps

2,6-Difluoro-alpha-methylbenzyl alcohol of (B) (14.9 g, 0.094 mol) is dissolved in chloroform (50 ml) and warmed to 60° C. Thionyl chloride (22.4 g, 0.19 mol) is now added dropwise. The whole is kept at 60° C. for 4 hours then stirred overnight at room temperature. Excess thionyl chloride and chloroform are then removed on a rotary evaporator, resulting in pure title product (16.6 g, 99.8%).
