実験手順
A mixture of 46 mg of (S)-2-(2,4-dioxo-1,4-dihydro-2H-pyrido[3,2-d]pyrimidin-3-yl)-butyric acid tert-butyl ester, 41 mg of 3-bromomethyl-4,6-dimethyl-1,2-benzoisothiazole and 111 mg of potassium carbonate is stirred at room temperature for 4 h. The reaction mixture is diluted with water and the product is filtered and washed with water. The isolated solid is purified by flash chromatography on silica gel to give 72 mg (99%) of (S)-2-[1-(4,6-dimethyl-benzo[d]isothiazol-3-ylmethyl)-2,4-dioxo-1,4-dihydro-2H-pyrido[3,2-d]pyrimidin-3-yl]-butyric acid tert-butyl ester.
