- Preparation method of velpatasvir intermediate
-
The invention provides a preparation method of a velpatasvir intermediate. According to the preparation method, ortho-toluidine is taken as an initial raw material, amino acetylation protection, Friedel-Crafts acylation, deamination protection, diazotization, and bromination are adopted so as to obtain 3-bromomethyl-4-bromoacetophenone; and alkylation with 7-hydroxy-1-tetralone, intramolecular coupling, and bromination are adopted so as to obtain 9-bromo-3-(2-bromoacetyl)-10, 11-dihydro-5H-benzo[d]naphtho[2,3-b]pyran-8(9H)-one. The yield and the purity of the velpatasvir intermediate preparedvia the preparation method are high, cost is low, and large size production is convenient to realize.
