- A method for preparing may compared to the department he intermediate and intermediate thereof and use thereof
-
The invention relates to the field of medicinal chemical synthesis, in particular to a cobicistat intermediate preparing method, an intermediate and application thereof. The cobicistat intermediate (a compound (4)) preparing method includes the steps that a compound (5) is prepared into an organic metal compound (5'), and the compound (5') reacts with a compound (6) to prepare the compound (4) (see the reaction process in the description). The new reaction raw material compound (5) or (6) is provided to obtain the new compound (4) preparing method, the overall yield of the reaction can be increased, usage of toxic reagents is avoided, side reactions are reduced, and the cobicistat intermediate preparing method is suitable for industrial production. Further, the compound (4) is used as the intermediate for preparing a compound (1), by-products in the prior art are avoided, usage of toxic reagents is avoided, cost is saved, and the intermediate is beneficial for environment maintenance and suitable for industrial production.
