Paragraph 0041; 0045-0048, (2021/11/19)
The invention relates to the field of organic synthesis, in particular to a preparation method of ortho-amino trifluoroacetophenone and derivatives thereof. The preparation of ortho-amino trifluoroacetophenone comprises three steps of amino protection, trifluoroacetylation and deprotection, the overall reaction condition is mild, the yield is high, and the method is suitable for large-scale production. In addition, on the basis of the preparation, substitution is carried out after amino diazotization, the ortho-amino trifluoroacetophenone derivative is further prepared, and the industrial application prospect is good.
