<p>The process consists in condensing (2-methyl-6,7,8,9-tetrahydro-4H-pyrido-[1,2-a] pyrimidin-3-yl)-acetaldehyde with 6-fluoro-3-piperidinyl)-1,2-benzisoxazole to yield the intermediate enamine, 3-[2-[4-(6-fluorobenzo[d]isoxazol-3-yl)-piperidin-1-yl]vinyl}-2-methyl-6,7,8,9-tetrahydro-pyrido [1,2,-a] pyrimidin-4-one followed by reduction of such an enamine.</p> |
