Step 1 4-Hydroxymethyl-1H-pyridin-2-one 2-Oxo-1,2-dihydropyridine-4-carboxylic acid methyl ester (1.8 g, 12.2 mmol), prepared as described in J. Org. Chem., 26, 428 (1961), was suspended in THF(100 ml). A small amount of DMF was added to help increase solubility. LiBH4 (61 mmol) was added and the reaction was stirred for 18 hours at room temperature. MeOH and H2 O are added to quench the reaction. The reaction is then concentrated to yield a yellow oil. Flash chromatography (5% MeOH/CHCl3 to 20% MeOH/CHCl3) yielded 4-hydroxymethyl-1H-pyridin-2-one as a white solid. 1 H NMR (400 MHz, CD3 OD) delta 7.38-7.36 (1H,d); 6.56 (s, 1H); 6.37-6.36 (d, 1H); 4.50 s, 2H).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,89937-77-9, its application will become more common.

LiH (78 mg) was suspended in DMF (5 ml), and a suspension of methyl-2-oxo-1,2-dihydropyridine-4-carboxylate (500 mg) in DMF (5 ml) was added dropwise thereto at room temperature. The suspension was stirred as it was, and a solution of 1-indo-2-methylpropane (506 mul) in DMF (5 ml) was added dropwise thereto over 10 min, followed by stirring at 50C for 15 hours. To the reaction solution was added 1M HCl at 0C, followed by extraction with EtOAc, and the organic layer was washed with saturated brine, dried over anhydrous MgSO4, and filtered, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (n-hexane:EtOAc=90:10 to 50:50) to obtain methyl-1-isobutyl-2-oxo-1,2-dihydropyridine-4-carboxylate (440 mg) as white powders.
