Reaction Steps
The product is prepared according to the procedure described in Example 1, using 100 mg of 2,2-dimethyl-7-morpholin-4-yl-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one and 0.94 ml of 4-methoxyphenethyl bromide, replacing the sodium hydride with caesium carbonate. After purification by silica column chromatography (eluent: dichloromethane/methanol: 98/02), 39 mg of 1-[2-(4-methoxyphenyl)ethyl]-2,2-dimethyl-7-morpholin-4-yl-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-5-one are obtained, the characteristics of which are the following:
