, (2017/10/13)
The invention provides preparation methods of a tyrosine kinase inhibitor and intermediates thereof, specifically preparation methods of N-[3-fluoro-4-[[6-methoxy-7-[oxy]quinolin-4-yl]oxy]phenyl]-N'-(4-fluorophenyl)cyclopropane-1,1-dicarboxamide (Foretinib), and analogs and intermediates thereof. 1,1-cyclopropane dicarboxylic acid diester is used as the raw material to prepare a compound of the formula VI; and the compound of the formula VI is hydrolyzed and then reacts with a compound of the formula VIII, so as to prepare the Foretinib and the analogs thereof. The condition of each reaction step is mild, the preparation method is easy to operate, the price of the raw materials is low, and thus the production cost is reduced, the yield is relatively high, and the preparation methods are suitable for industrialized production.

, (2017/01/19)
The present invention provides a preparation method of a tyrosine enzyme inhibitor Foretinib. The method is as below: subjecting 1,1-cyclopropyl dicarboxylic acid diethyl ester to selective hydrolysis; amidating with p-fluoro aniline to obtain a compound shown in a formula 4; hydrolyzing and amidating with 4-amino-2-fluorophenol to obtain a compound shown in a formula 6; conducting substitution on 4-chloro-6-methoxy-7-quinolinol and N-(3-chloropropyl) morpholine to obtain a compound shown in formula 8; conducting substitution on the compound in formula 6 and compound shown in the formula 8 to obtain a target product N-[3-fluoro-4-({6-(methyl oxy)-7-[(3-morpholine-4-yl phenyl)-oxy] quinoline-4-yl}oxy)phenyl]-N'-(4-fluorophenyl) cyclopropane-1,1-dicarboamide crude product. The crude product is re-crystallized in an ethanol / acetone solution to obtain a high purity product with an overall yield of 44-55%. The method has the advantages of easy and feasible process, easily available raw materials, high overall yield and good product quality, and is applicable to industrial production.
