Procedure

5 g (0.018 mol) of 1-(2-Trifluoromethyl-thiazol-4-yl)-1-hydroxy-2-bromoethane are suspended in 4 ml of 50% strength sodium hydroxide solution and stirred for 5 minutes. The mixture is then diluted with ice-water and extracted by shaking with methylene chloride. The organic phase is dried over sodium sulphate and concentrated in vacuo at 20° C., and the resulting oil is purified on a silica gel column using methylene chloride as eluant.
