Procedure
A mixture of 2,6-dichloro-5-fluoro-nicotinonitrile (830 mg, 4.34 mmol), 3-amino-N-methoxy-4-methyl-benzamide (576 mg, 3.2 mmol) and triethylamine (0.5 mL) in acetonitrile (10 mL) was heated to 70° C. overnight. Then the solvent was removed under reduced pressure and the reaction mixture was partitioned between water and ethyl acetate. The organic layer was dried (sodium sulfate) and concentrated under reduced pressure. The product (220 mg, 21%) was isolated after purification by silica gel chromatography. C15H12ClFN4O2 MS m/e=335 (M+H).
