反応手順
150 mg of 7-chloro-1-(2-isopropoxyethyl)-2,2-dimethyl-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one in 2 mL of morpholine are heated with the microwave oven to 80° C. for 45 mins. The crude is purified by flash chromatography on silica gel (CH2Cl2 100% to CH2Cl2/MeOH, 92/8). 0.085 g (yield=60%) of 1-(2-isopropoxyethyl)-2,2-dimethyl-7-(morpholin-4-yl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one are obtained as a beige solid and including the following characteristics:
