Heat a solution of 1-(3-amino-4-fluorophenyl)propan-2-one (0.34 g, 2.034 mmol), 4-amino-6-chloronicotinaldehyde (0.318 g, 2.034 mmol) and KOH (0.057 g, 1.017 mmol) in EtOH (12 mL) at 60° C. for 1 h. Cool the mixture to RT, add brine and extract with EtOAc (3×). Dry the combined organics over MgSO4, concentrate to dryness and purify via silica gel chromatography (EtOAc/Hex) to afford the title compound (353 mg, 60%). MS (ESI) m/z: 288.1 (M+H+).
