Procedure
Combine 4-methoxybenzyl alcohol (45.4 mmol), N,N-diisopropylethylamine (12.9 g, 100 mmol), and acetonitrile (60 mL). Cool in an ice bath. Add methanesulfonyl chloride (6.76 , 49.0 mmol). After 2 hours, partition the reaction mixture between water and ethyl acetate. Separate the layers and extract the organic layer with 1 M hydrochloric acid solution and then a saturated solution of sodium bicarbonate. Dry the organic layer over Na2SO4, filter, and evaporate in vacuo to give the title compound.
