- PROCESS FOR PREPARATION OF CERITINIB
-
The present application relates to a process for preparation of ceritinib and intermediates thereof. Specifically, the present application relates to a process for preparation of N-(4-(1-benzyl- 1,2,3,6-tetrahydropyridin-4-yl)-2-isopropoxy-5-methylphenyl)acetamide (VC) comprising treating N-(4-(bromomethyl)-2-isopropoxy-5-methylphenyl)acetamide (IIID) with 1- benzylpiperidin-4-one (IVA). The present application also relates to a process for conversion of N-(4-(1-benzyl-1,2,3,6-tetrahydropyridin-4-yl)-2-isopropoxy-5-methylphenyl)-acetamide (VC) to ceritinib or an acid-addition salt thereof.

- Ceritinib synthesis intermediate and preparation method thereof
-
The invention provides a synthesis intermediate 8 of an anti-tumor drug ceritinib, a preparation method thereof, and an application of the intermediate 8 in synthesizing ceritinib. The preparation method of the intermediate 8 comprises the following steps: step (1), a compound 1 and an acid HX are subjected to salt formation, such that a compound 7 is obtained; step (2), the compound 7 is reduced through sodium borohydride, such that the compound 8 is obtained. The reaction formula is as the following. With prior arts, expensive platinum oxide is needed as a hydrogenation catalyst for preparing an intermediate 2 in a next step. With the intermediate 8, the above problem is avoided. Therefore, the intermediate 8 is suitable to be used in industrialized production of ceritinib.
