Reaction Conditions

Reaction Steps

4.4 ml of freshly distilled boron trifluoride are added dropwise, while cold, to 1.1 g of dry sodium borohydride suspended in 35 ml of freshly distilled tetrahydrofuran. The reaction mixture is stirred at 0° C. for 2 hours and then 3.5 g (0.01 mol) of the compound obtained in Step g in 100 ml of tetrahydrofuran are added. The mixture is then heated under reflux for one hour and then 50 ml of a 2N hydrochloric acid solution are added while cold. The mixture is neutralised with sodium hydroxide and then extracted with ether. Customary treatment of the organic phase yields a crude product which is purified over a silica gel column (eluant: trichloromethane). 1 g of the pure desired product is obtained in the form of a colourless oil.
