Procedure

2-{4-(benzyloxy)-3-[(1R)-3-(diisopropylamino)-1-phenylpropyl]phenyl}ethanol (Prepared according to WO1998/43942, 1.0 g, 2.25 mmol) was dissolved in dichloromethane (20 ml) and N,N-diisopropyl ethylamine (1.8 ml, 10 mmol) added. The solution was then cooled to 0° C. and methanesulphonyl chloride (0.42 ml, 5.4 mmol) was added. After stirring for 2 hours at 0° C. the mixture was diluted with dichloromethane (20 ml) and washed with water (50 ml), brine (50 ml) and then dried (magnesium sulphate) and the solvent removed in vacuo to yield the title compound as a yellow oil, 1.56 g.
