2-Methyl-5-pyrimidinecarboxaldehyde (8 g, 66 mmol, compound 44b) was dissolved in methanol (100 mL) at 0°C and sodium borohydride (7.5 g, 197 mmol) was slowly added. The reaction temperature was maintained in the range of 0-15°C and the reaction mixture was stirred for 3 hours. Upon completion of the reaction, the reaction was quenched with saturated ammonium chloride solution (30 mL) and subsequently extracted with ethyl acetate (20 mL x 3). The organic layers were combined, dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. Purification of the residue by silica gel column chromatography afforded (2-methylpyrimidin-5-yl)methanol (4.1 g, 51% yield, compound 44c) as a white solid.

with sodium tetrahydroborate;ethanol at 20; for 3 h;
Steps:
24.1 Step 1 (2-methylpyrimidin-5-yl)methanol
Step 1 (2-methylpyrimidin-5-yl)methanol To a solution of 2-methylpyrimidine-5-carboxylic acid (150 mg, 1.23 mmOl) in ethanol (5 mL) was added sodium borohydride(93 mg, 2.46 mmol). The mixture was stirred at room temperature for 3 h. It was quenched with aqueous HC1 (2 N, 2 mL), extracted with DCM, dried over sodium sulfate, filtered and concentrated give the yellow oil product (2-methylpyrimidin-5-yl)methanol (95 mg, 62.6%). LCMS MH+ 125.
