- A method for preparing color Switzerland for Nepal
-
The invention discloses a method for preparing ceritinib, belonging to the field of chemical pharmacy. The method comprises the following steps: by taking 3-bromine-4-methylphenol as an initial raw material, performing phenolic hydroxyl isopropylation, nitration, coupling and reduction reaction, obtaining a midbody 1, by further taking o-nitro fluorobenzene as another initial raw material, performing isosulfhydrylation, oxidation, reduction and pyrimidine, obtaining a midbody 2, performing coupling reduction on the midbody 1 and the midbody 1, obtaining ceritinib which is protected by BOC acid anhydride, and finally removing a t-butyloxycarboryl protecting group, and obtaining ceritinib. The method is simple and feasible to operate, relatively high in yield, small in pollution and applicable to industrial production.

- 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 intermediate and preparation method and application thereof
-
The present invention discloses a ceritinib intermediate and a preparation method and application thereof. The ceritinib intermediate has a structure shown as a formula I, R and R2 are as defined in the specification and claims. The ceritinib intermediate is prepared from a compound of a formula 1 and a benzyl halide compound by substitution reaction and then reduction. After further reduction of the nitro by catalytic hydrogenation and removal of amino-protection, the compound of the formula I is reacted with a compound of a formula III to obtain ceritinib. According to the method, raw materials are readily available and inexpensive, the method does not require special equipment, production cost is greatly reduced, and the method is suitable for industrial application.
