Reaction Steps

To a suspension of methyl 2-fluoro-4-[3-(methylsulfinyl)-1,2,4-triazin-6-yl]benzoate (0.19 g, 0.00064 mol) in tetrahydrofuran (20 mL) was added hydrazine hydrate (63 μL, 0.0013 mol) slowly. The mixture was stirred at RT for 1.5 h. The mixture was concentrated under reduced pressure to yield the desired product. Analytical LCMS: (M+H)+=264.1.
