This invention provides improved processes for the preparation of 5-chloro-2-methyl-2,3,3a 12b-tetrahydro-1H-dibenzo[2,3:6,7]oxepino[4,5-c]pyrrole, asenapine. These processes allow the preparation of asenapine at industrial scale in good yields and high stereoselectivity.
本发明提供了改进的工艺,用于制备5-
氯-2-甲基-2,3,3a 12b-四氢-1H-二苯并[2,3:6,7]氧杂[4,5-c]
吡咯,即阿塞那平。这些工艺允许在工业规模下以良好的产率和高立体选择性制备阿塞那平。
