布南色林中间体的制备方法
摘要：
本发明公开一种布南色林中间体的制备方法，该方法按照如下两个步骤依次进行：a)3-(4-氟苯基)-3氧代丙腈反应生成3-(4-氟苯基)-3氧代丙酰胺；b)3-(4-氟苯基)-3氧代丙酰胺和环辛酮反应得到4-(4-氟苯基)-5，6，7，8，9，10-六氢环辛烷并吡啶-2(1H)-酮。按照本发明方法，制备4-(4-氟苯基)-5，6，7，8，9，10-六氢环辛烷并吡啶-2(1H)-酮的收率由17％提高至80％左右。
摘要（英）：

The invention discloses a preparing method of blonanserin intermediate. The method is processed according to the following two steps of: (a) producing 3-(4-fluorophenyl)-3 oxo-propanamide through the reaction of 3-(4-fluorophenyl)-3 oxypropionitrile; and (b) obtaining 4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro cyclooctane pyridine-2-(1H)-ketone through the reaction between the 3-(4-fluorophenyl)-3oxo-propanamide and cyclooctanone. The yield coefficient of the 4-(4-fluorophenyl)-5,6,7,8,9,10-hexahydro cyclooctane pyridine-2-(1H)-ketone prepared by using the method is increased to about 80 percent from 17 percent.
