Komponenten

Versuchsvorschrift

A mixture of 6-methoxy-2-methylpyridin-3-amine (10.0 g, 0.0724 mol) in tetrahydrofuran (50 mL) and aqueous saturated sodium hydrogen carbonate (50 mL) was added thiophosgene (6.62 mL, 0.0868 mol) at 0° C. The reaction mixture was stirred at room temperature for 1 hr. The mixture was extracted with ethyl acetate (×3). The combined organic layer was washed with brine (×1), dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. To the residue was added n-hexane and the precipitate was removed by filtration and the filtrate was concentrated in vacuo. The residue was washed with cold-n-hexane to give the title compound as a pale yellow solid (5.35 g, 0.0297 mol, 41%).
