실험 절차

1.27 g (0.034 mole) of sodium borohydride in 10 ml of water are added to 16.4 g (0.1 mole) of tert.-butyl 5-pyrimidinyl ketone in 100 ml of methanol at room temperature. The reaction mixture is stirred at room temperature for 1 hour and concentrated in vacuo, the residue is distilled in methylene chloride and the solution is concentrated again in vacuo. 15.8 g (95% of theory) of 5-(1-hydroxy-2,2-dimethyl-propyl)-pyrimidine of melting point 93°-95° C. are obtained.
