Procedure

A solution of methanesulfonyl chloride (3.4 mL, 5.0 g, 44 mmol) in DCM (15 mL) was added slowly to a cooled (−5° C.) mixture of 4-[1-(3,4-dimethoxyphenoxy)-4-hydroxybutyl]benzonitrile (see step (ii) above; 11 g, 34 mmol) and triethylamine (7 mL, 5.2 g, 50.6 mmol) in DCM (50 ML), during which addition the temperature did not rise above 2° C. Stirring was continued at between 0 and 5° C. for a further 2 h before water was added. The resulting organic layer was separated, and washed with water, separated again and then dried to give the subtitle compound in 100% yield.
