実験手順: A cooled (0° C.), stirred suspension of (2-chloro-4-methanesulfonyl-phenyl)-methanol (19.1 g, 0.087 mol) in diethyl ether (250 ml) under an inert atmosphere, is treated with phosphorus tribromide (5.2 ml, 0.029 mol) and allowed to stir and warm to room temperature overnight. The resulting mixture is diluted with water (100 ml) and the organic portion is separated and dried over NaOH pellets for 5 minutes. The solvent is removed in vacuo and the resulting crude residue is loaded on a pre-packed Isolute™ silica column and eluted with iso-hexane/ethyl acetate (4:1) to yield the titled compound as a white powder. to stir warm to room temperature overnight the organic portion is separated dried over NaOH pellets for 5 minutes The solvent is removed in vacuo eluted with iso-hexane/ethyl acetate (4:1)

実験手順: To a stirred dispersion of 2-chloro-4-methanesulfonyl-benzaldehyde (25 g, 0.11 mol) in absolute ethanol (120 ml) is added sodium borohydride (4.6 g, 0.12 mol) whilst cooling with an ice-bath to maintain room temperature. After stirring at room temperature for 3 hours, the reaction mixture is poured carefully onto ice-water (600 ml) and acidified to pH 1-2 with 1N HCl. The resulting suspension is extracted with ethyl acetate (400 ml) and the organic portions are combined, washed with brine, dried (MgSO4) and concentrated in vacuo. The resulting crude product is dried in a vacuum oven at 40° C. overnight to yield the titled product which is used crude in the next step. whilst cooling with an ice-bath the reaction mixture is poured carefully onto ice-water (600 ml) The resulting suspension is extracted with ethyl acetate (400 ml) washed with brine dried (MgSO4) concentrated in vacuo The resulting crude product is dried in a vacuum oven at 40° C. overnight
