Procedure

The title compound was prepared in accordance with the general method of Example 199(D), from N-methyl-4-(pyridin-2-yl)but-3-yn-1-amine (50 mg, 0.31 mmol) and 2,3-difluorobenzoyl chloride (72 mg, 0.41 mmol). The crude residue was purified over silicagel chromatography (prepacked 10 g silicagel column, DCM/MeOH: from 100/0 to 98/2 as eluent) to afford 67 mg of 2,3-difluoro-N-methyl-N-(4-(pyridin-2-yl)but-3-ynyl)benzamide as a brown oil (Yield: 71%).
