실험 절차

A mixture of dimethyl [[6-(3-cyclopentylpropionamido)-4-quinazolinylamino]methylene]propanedioate (6.9 g) in diphenyl ether (53 ml) was stirred at 255° C. for 15 minutes and cooled to ambient temperature. The resulting solid was collected, washed with hexane and dried. There was obtained methyl 4-oxo-10-(3-cyclopentylpropionamido)-4H-pyrimido[1,2-C]quinazoline-3-carboxylate (4.5 g).
