Sodium borohydride → (6-(Dimethylamino)-5-methylpyrimidin-4-yl)methanol

Participants

Reaction Steps

To a stirred solution of ethyl 6-(dimethylamino)-5-methylpyrimidine-4-carboxylate (23) (0.4 g, 1.91 mmol) in MeOH (10 mL) was added in portionwise NaBH4 (0.14 g, 3.82 mmol) at 0° C. and the mixture was stirred for 16 h at RT. The solvent was evaporated under the reduced pressure and the reaction mixture was poured in to water (20 mL) and extracted with ethyl acetate (3×30 mL). The combined organic layer was washed with water, brine, dried over sodium sulfate, and concentrated at reduced pressure to yield (6-(dimethylamino)-5-methylpyrimidin-4-yl)methanol (24); 0.1 g, (31.3%).
