A process for the preparation of key intermediate asenapine

The invention provides a chemical synthesis method, in particular to a preparation method of a key intermediate [formula (III)] compound of asenapine capable of serving as a schizophrenia drug. In an anhydrous system, the intermediate [formula (III)] compound is obtained through dehydration of an intermediate [formula (II)] compound and anhydride under the action of a catalyst. The invention further provides a novel method for preparing asenapine by the intermediate [formula (III)]. The provided method has the advantages of simple operation, high yield, environment-friendliness, lower cost, stable technology and the like.
