PROCEDURE

实验过程

A solution of 3-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-6,7,8,9-tetrahydro-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (0.048mol) in ethanol (600ml) was added to a solution of pamoic acid (0.048mol) in N,N-dimethylformamide (400ml). The mixture was stirred for 3 hours. The resulting precipitate was filtered off by suction, washed with ethanol and dried, yielding 31 g (81%) of 3-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-6,7,8,9-tetrahydro-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one 4,4'-methylenebis[3-hydroxy-2-naphthalenecarboxylate](1:1); mp. 269.2° C.
