実験手順

Concentrated sulfuric acid (8 mL) was added to 5-(3-methylpyridin-2-ylthio)-3-(2-methylpyridin-3-yloxy)picolinonitrile (1.40 g, 4.19 mmol). The reaction was stirred over the weekend, then poured onto ice (100 g), cooled in an ice bath and made basic to pH 10 with 50% NaOH. The reaction mixture was extracted with ethyl acetate, washed with brine, dried (MgSO4), and concentrated to afford 5-(3-methylpyridin-2-ylthio)-3-(2-methylpyridin-3-yloxy)picolinamide (1.40 g, 3.97 mmol, 94.9% yield) as a colorless oil which became a white crystalline solid overnight under vacuo.
