Ammonia → 1-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)thiourea

Participants

Reaction Steps

Step F (4): Methanolic ammonia (1.0 M, 100 mL, 100 mmol) was added to a flask charged with 1-(4-isothiocyanato-2-methoxyphenyl)-3-methyl-1H-1,2,4-triazole (3.91 g, 15.88 mmol) in a ice-water bath. After the addition was complete, the resulting slurry was stirred for 10 min and then allowed to warm to rt. After 24 h, the reaction mixture was concentrated to dryness in vacuo to afford 1-(3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenyl)thiourea (4.18 g, 13.81 mmol, 87% yield) as a white solid. LC-MS (M+H)+ 264.0.
