Versuchsvorschrift
25 g (115 mmol) of 5-isopropylcarbonyl-4-trifluorometylpyrimidine was dissolved in 100 ml of ethanol, and under cooling with ice, 6 g (69 mmol) of a borane-tert-butylamine complex was added, followed by stirring for 2 hours. Further, 20 ml of acetone was added, followed by stirring for 0.5 hour. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography (developing solvent/n-hexane:ethyl acetate=1:1) to obtain 22 g (yield: 87%) of 5-(1-hydroxy-2-methylpropyl)-4-trifluoromethylpyrimidine as slightly yellow liquid (nD20=1.4481)
