600 mg (5.41 mmol) of powdered calcium chloride are added to a suspension of 400 mg (10.6 mmol) of sodium borohydride in 20 ml of THF, and the mixture is stirred at room temperature for 1.5 hours. A solution of 751 mg (3.29 mmol) of methyl 3-(5-methylpyrimidin-2-yl)benzoate in 10 ml of THF is added dropwise to this suspension with stirring, and the mixture is stirred at room temperature for 18 hours. 10 ml of 1 N NaOH, water and dichloromethane are added to the reaction mixture, which is then filtered. The organic phase of the filtrate is separated off, dried over sodium sulfate and evaporated. The residue is chromatographed on a silica-gel column with dichloromethane/methanol as eluent: [3-(5-methylpyrimidin-2-yl)phenyl]methanol as colourless solid; LCMS 201.
