실험 절차

A mixture of 1.75 g of (R)-3-(2,4-dioxo-1,4-dihydro-2H-pyrido[3,2-d]pyrimidin-3-yl)-pentanoic acid methyl ester, 2.5 g of trimethyl-(1,4,6-trimethyl-1H-indol-3-ylmethyl)-ammonium iodide and 1.7 g of potassium carbonate in 50 mL of N,N-dimethylformamide is heated at 65° C. for 3 h. The resulting mixture is diluted with water and the product is extracted with ethyl acetate. The organic layer is washed with brine, dried (sodium sulfate) filtered and concentrated. The residue is purified by flash chromatography on silica gel to give 1.0 g (35%) of (R)-3-[2,4-dioxo-1-(1,4,6-trimethyl-1H-indol-3-ylmethyl)-1,4-dihydro-2H-pyrido[3,2-d]pyrimidin-3-yl]-pentanoic acid methyl ester.
