Step 3. Synthesis of 5-pyrimidinemethanol. 5-Pyrimidinecarboxaldehyde (2 g, 18.50 mmol, 1.00 eq.) and sodium borohydride (2 g) were dissolved in methanol (100 mL) and the reaction was stirred for 30 min at 0-10 °C. Upon completion of the reaction, the solvent was removed by vacuum concentration and the resulting residue was purified by silica gel column chromatography with dichloromethane/methanol (50:1, v/v) as eluent to give 1.2 g (59% yield) of the target compound 5-pyrimidine methanol as a light yellow solid. Mass spectrometry result: m/z = 111.0 [M + H]+.
