2-(1-chloroethyl)-1,3-difluorobenzene

Conditions: temp:75.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2,6-Difluoro-alpha-methylbenzyl chloride (16.6 g, 0.094 mol) is dissolved in ethanol (40 ml) and warmed to 75° C. A 40 percent solution of sodium omadine (38.5 g, 0.103 mol) is added dropwise over a period of 30 minutes maintaining a reaction temperature of 75° C. throughout. Once the addition is complete, the reaction mixture is kept between 75° C. and 80° C. for 2 hours. Thereafter the mixture is quenched in ice-water and crude product is filtered off. After recrystallization with ethyl acetate pure title product (10.65 g, 42.4%) is obtained; Melting Point 158°-160° C. maintaining a reaction temperature of 75° C. throughout Once the addition Thereafter the mixture is quenched in ice-water crude product is filtered off After recrystallization with ethyl acetate pure title product (10.65 g, 42.4%) is obtained

Conditions: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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%). Excess thionyl chloride and chloroform are then removed on a rotary evaporator
