A mixture of methyl 2-fluoro-4-(3-hydrazino-1,2,4-triazin-6-yl)benzoate (0.17 g, 0.64 mmol) and 1-quinolin-6-ylcyclopropanecarbaldehyde (0.13 g, 0.64 mmol) in ethanol (10 mL) and acetic acid (1 mL) was stirred at RT for 2 h. The mixture was concentrated. The residue was dissolved in methylene chloride (5 mL). To the solution was added iodobenzene diacetate (230 mg, 0.71 mmol) with stirring. The mixture was stirred at RT for 2 h then concentrated. The residue was flash chromatographed on a silica gel column to give the desired product (150 mg). Analytical LCMS: (M+H)+=441.0.
