Vorschrift

To 5-methoxypyridin-2-amine (5 g, 40 mmol) in dioxane (40 mL) was added ethoxycarbonyl isothiocyanate (5.23 mL, 44.3 mmol). The reaction mixture was stirred at room temperature overnight. The mixture was concentrated in vacuo to afford 5-methoxypyridin-2-amine ethoxycarbonyl thiourea (10.28 g, 40.3 mmol, 100% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 12.03 (1 H, br. s.), 11.37 (1 H, br. s.), 8.53 (1 H, br. s.), 8.11 (1 H, d, J=2.93 Hz), 7.50 (1 H, dd, J=8.97, 3.11 Hz), 4.22 (2 H, q, J=7.07 Hz), 3.84 (3 H, s), 1.26 (3 H, t, J=7.14 Hz). MS (LC/MS) R.T.=2.40; [M+H]+=256.1.
