반응 단계
The product is prepared according to the procedure described in stage k of Example 1, using 100 mg of (2S)-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one (Example 1j) and 106 mg of 2-bromo-4-(bromomethyl)-1-fluorobenzene, replacing the sodium hydride with 214 mg of caesium carbonate. After purification by preparative HPLC/MS (method C), 50 mg of (2S)-1-(3-bromo-4-fluorobenzyl)-2-methyl-7-(morpholin-4-yl)-2-(trifluoromethyl)-2,3-dihydroimidazo[1,2-a]pyrimidin-5(1H)-one are obtained in the form of a off-white semi-solid, the characteristics of which are the following:
