Reaction Steps
A mixture of 6-(4-bromo-3-fluorophenyl)-3-(methylthio)-1,2,4-triazine (1.15 g, 0.00383 mol) and hydrazine hydrate (0.74 mL, 0.015 mol) in ethanol (50 mL) was heated at 90° C. for 20 h. After cooling, the formed precipitate was collected by filtration, and dried in-vacuo to afford the desired product (0.845 g, 77.6%).
