Reaction Steps

Step O (4): Methanolic ammonia (2.0 M, 25 mL, 50 mmol) was added to a flask charged with 2-(4-chloro-1H-imidazol-1-yl)-5-isothiocyanato-3-methoxypyridine (2.5 g, 9.37 mmol). After 16 h, the reaction mixture was concentrated in vacuo to afford 1-(6-(4-chloro-1H-imidazol-1-yl)-5-methoxypyridin-3-yl)thiourea (2.24 g, 7.89 mmol, 84% yield). LC-MS (M+H)+ 283.9. 1H NMR (500 MHz, DMSO-d6) δ ppm 8.24 (d, J=1.83 Hz, 1 H) 8.12 (d, J=2.14 Hz, 1 H) 8.09 (d, J=2.14 Hz, 1 H) 7.79-7.82 (m, 1 H) 3.90-3.95 (m, 3 H).
