Reaction Conditions

Reaction Steps

Within 10 min was dropped 31.6 ml (37.9 mmol) of 1.2 M DIBALH solution in toluene to a dry ice cooled (−50° C.) solution of 4.25 g (12.64 mmol) 4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidine-5-carboxylic acid ethyl ester in 50 ml of THF. The reaction mixture was stirred 30 min at −50° C. and after letting rise the temperature to RT, the reaction was stirred for 1 h at RT. The reaction mixture was taken up in ether and washed with 1N HCL and water. The solvent was removed under reduced pressure to give 3.72 g of pure [4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-yl]-methanol.
