反応手順
The product is prepared according to the procedure described in Example 22, but using 100 mg of (8S)-2-(morpholin-4-yl)-8-(trifluoromethyl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one, 57 mg of 1-(chloro-methyl)-3-methoxybenzene and 214 mg of caesium carbonate in 2 ml of dimethylformamide. After treatment, the residue is stirred into acetonitrile. The solid is spin-filter-dried, rinsed with diethyl ether and then dried under a vacuum bell jar. 111 mg of (8S)-9-(3-methoxybenzyl)-2-(morpholin-4-yl)-8-(trifluoromethyl)-6,7,8,9-tetrahydro-4H-pyrimido[1,2-a]pyrimidin-4-one are thus obtained in the form of a white solid, the characteristics of which are the following:
