<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-fluoro -benzo[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> |
