실험 절차

To a solution of 4-(((tert-butyldimethylsilyl)oxy)methyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (3.8 g, 13.7 mmol) in methanol (200 mL), Raney Ni and ammonia (20 mL) were added and reaction stirred under hydrogen balloon pressure for 15 h. On completion, reaction mixture was filtered through a celite bed and the filtrate concentrated to obtain 3-(aminomethyl)-4-(((tert-butyldimethylsilyl)oxy)methyl)-6-methylpyridin-2(1H)-one as an off white solid (3.2 g, 83.1%).
