1-Propanol → 2-Methyl-4-propoxypyridine-1-oxide

関与物質

反応手順

To a solution of sodium n-propoxide solution prepared by dissolving sodium (1.7 g) in n-propanol (200 ml) was added to a hot solution of 2-methyl-4-nitropyridine-1-oxide (5.2 g) in n-propanol (210 ml). The mixture was stirred for ten minutes, then n-propanol was evaporated off. To the residue was added chloroform under ice-cooling, and insoluble materials were removed by means of celite filtration. From the resultant solution was removed chloroform by evaporation. The residue was subjected to a silica-gel column chromatography, followed by elution with 10% methanol-chloroform to yield 2-methyl-4-propoxypyridine-1-oxide (4.7 g) as an oily substance.
