A key intermediate for the preparation method of Eptazocine

-

Paragraph 0019-0020; 0022-0023, (2017/11/16)

The present invention discloses a dezocine key intermediate preparation method, 7-methoxy-2-tetralone is used as a starting material for first benzyl-site methylation and then ortho alkylation of the carbonyl group, the dezocine key intermediate can be prepared by three strategies of stepwise synthesis, two-step and one-pot methods. The dezocine key intermediate preparation method has the advantages of simple synthetic route, less steps, high yield simple operation, great reduction of the synthesis cycle, mild reaction conditions, and improvement of the safety of the technology, the low raw material cost and easy industrialization. The preparation cost is greatly reduced by the simple synthesis method, the patient dosage cost is reduced, the national social security spending can be reduced to some extent, and some of the social and economic benefits are produced.
