Sodium Sulfite → 6-Methylpyridine-3-carbonitrile 1-oxide

関与物質

反応手順

6-Methylnicotinonitrile (3.68 g, 31.15 mmol) is dissolved in chloroform (60 ml). 3-Chloroperoxybenzoic acid (7.53 g, 32.71 mmol) is added dropwise as a solution in chloroform (60 ml), and the solution is stirred at room temperature overnight. Sodium sulphite (2.92 g, 23.17 mmol) is added, and the resulting mixture is stirred for one hour. The reaction is quenched with saturated sodium bicarbonate solution, and the product is extracted with chloroform (500 ml). The organic phase is washed with brine, dried over magnesium sulphate monohydrate, filtered and concentrated in vacuo. The residue is used without further purification.
