실험 절차

0.17 g of 7,7-dimethyl-2-(morpholin-4-yl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]-pyrimidin-4-one are solubilized in anhydrous DMF. 0.03 g of 60% NaH are added and stirring is performed for 30 mins. 0.24 g of 2-isopropoxyethyl methanesulfonate are added and the mixture is heated with reflux for 3 h. After returning to RT, the mixture is poured in a water/ice/AcOEt mixture. The organic phase is decanted, washed with a solution saturated with NaCl and then dried with magnesium sulfate. The solvents are evaporated. The crude is purified by flash chromatography on silica gel (CH2Cl2/MeOH, 95/5). 0.08 g (yield=35%) of 9-(2-isopropoxyethyl)-7,7-dimethyl-2-(morpholin-4-yl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one are obtained as a white powder including the following characteristics:
