Reaction Steps
N-(2-Fluoro-4-iodo-phenyl)-malonamic acid ethyl ester (20.5 g, 58.4 mmol), 4-chloromethyl-pyrimidine (5.0 g, 38.9 mmol) and potassium hydroxide (3.28 g, 58.4 mmol) were dissolved in IMS (200 mL). The reaction mixture was stirred at room temperature for 16 hours then concentrated in vacuo. The resultant residue was dissolved in ethyl acetate (30 mL), washed with water (20 mL) and the aqueous fraction extracted twice with ethyl acetate (2×10 mL). The combined organic fractions were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 10-40% ethyl acetate in cyclohexane) to yield the title compound as an off-white solid (6.9 g, 39%). LCMS (Method B): RT=3.29 min, M+H+=444.
