実験手順

A preferred process for preparing 2-(1-azabicyclo[2.2.2]oct-3-yl)-2,4,5,6-tetrahydro-1H-benz[de]isoquinolin-1-one is that in which the 2-(1-azabicyclo[2.2.2]oct-3-yl)-3-hydroxy-2,3,3 a,4,5,6-hexahydro-1H-benz[de]isoquinolin-1-one is 2-(1-azabicyclo[2.2.2]oct-3S-yl)-3-hydroxy-2,3,3a,4,5,6-hexahydro-1H-benz[de]isoquinolin-1-one and is dehydrated to give (S)-2-(1-azabicyclo[2.2.2]oct-3-yl)-2,4,5,6-tetrahydro-1H-benz[de]isoquinolin-1-one, preferably wherein the dehydration is catalyzed with hydrochloric acid or sulfuric acid, and the (S)-2-(1-azabicyclo[2.2.2]oct-3S-yl)-3-hydroxy-2,3,3a,4,5,6-hexahydro-1H-benz[de]isoquinolin-1-one is prepared by the preferred process described above.
