2-[(4-fluorophenyl)methoxy]ethyl methanesulfonate

Conditions: temp:-5.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 2-(4-fluorobenzyloxy)-ethanol (5.11 g, 30.0 mmol, from step (i) above) in methylene chloride (60 mL) was cooled to −10° C. Triethylamine (5.0 mL, 36 mmol) was added followed by methanesulfonyl chloride (3.78 g, 33.0 mmol) and the reaction mixture was stirred at −5° C. for 2 h. The reaction mixture was diluted with methylene chloride (200 mL) and the organic phase was washed with water (2×75 mL) and brine (75 mL), dried over MgSO4, and concentrated in vacuo to give 7.16 g (96%) of the title compound as a yellow oil. the organic phase was washed with water (2×75 mL) and brine (75 mL) dried over MgSO4 concentrated in vacuo
