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 3,5-dimethylisoxazole-4-sulfonyl chloride (79 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 17 mg of N,3,5-trimethyl-N-(4-(pyridin-2-yl)but-3-ynyl)isoxazole-4-sulfonamide as a brown oil (Yield: 17%).
