Reaction Steps

CH3SO2NHNH2 (79.5 mg, 1.1 equiv) and i-Pr2NEt (225 μL, 2 equiv) were added to a solution of 2-(4-chloro-phenoxycarbonylamino)-4-isopropyl-5-(2-methyl-2H-pyrazol-3-yl)-benzoic acid methyl ester (281 mg, 0.65 mmol) in dioxane (8 mL). The mixture was stirred for 16 h (TLC control) at 80° C. The mixture was evaporated to dryness. The crude product was purified by flash chromatography (MeOH/DCM (1:9)) to provide N-[7-isopropyl-6-(2-methyl-2H-pyrazol-3-yl)-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl]-methanesulfonamide as a white solid (120 mg, 48%) (ESI-MS: m/z 378 [M+H]+, rt 4.20 min).
