Description

One treats auspicious new intermediate for Buddhist nun (Ceritinib) of non-small cell lung cancer drug color and preparation method thereof
Technical field
The present invention relates to the chloro-N2-of medical compounds 5-(2-isopropoxy-5-methyl-4-(piperidin-4-yl) phenyl)-N4-(2-(isopropelsulfonyl) phenyl) pyrimidine-2; (color is auspicious for Buddhist nun for 4-diamidogen; and the preparation method of the chloro-N-of key intermediate 2,5-bis-(2-(isopropelsulfonyl) phenyl) pyrimidine-4-amine LDK378).
The auspicious chemistry for Buddhist nun of color is called: the chloro-N2-of 5-(2-isopropoxy-5-methyl-4-(piperidin-4-yl) phenyl)-N4-(2-(isopropelsulfonyl) phenyl) pyrimidine-2,4-diamidogen, chemical constitution is as follows.
Background technology
Color is auspicious for Buddhist nun (Ceritinib, LDK378), is that commodity are called Zykadia by the former one ground of Novartis (Novartis) company little molecule ALK tyrosinase inhibitorTM. In March, 2013, FDA authorizes its " breakthrough medicine " status according to its I phase clinical trial results, obtain FDA approval listing, the treatment of Metastatic Nsclc patient positive for anaplastic lymphoma kinase ALK Alk receptor tyrosine kinase (ALK), that fail to respond to any medical treatment for Buddhist nun (Crizotinib) on April 29th, 2014 through gram azoles.
WO2008/073687A1 reports the auspicious synthetic method for Buddhist nun of color, and its synthetic route is as follows:
With compound 1 for initiation material, obtain compound 2 through nitrated. Compound 2 fluorine when cesium carbonate is obtained compound 3 by isopropoxy replacement. Compound 3 and 4-pyridine boronic acid occur Suzuki coupling to obtain compound 4. Compound 4 is reduction nitro and pyridine under platinum dioxide exists; Then Boc protection 5 is gone up. Another side chain is with compound 6, and compound 7 is initiation material, and condensation obtains compound 8. There is Buchward coupling in compound 5 and compound 8, then slough Boc anhydride again, obtain product color auspicious for Buddhist nun under palladium-Xantphos condition.
List of references WO20110/140338; HelveticaChimicaActa; Vol.63; Nb.6; (1980): the synthetic method that 1412-1429 provides compound 7 is as follows:
The former condensation condition grinding the compound 6 and compound 7 provided in patent, is not suitable for iodine. This step condensation reaction uses sodium hydride to make alkali, and along with the increasing of reaction scale, reaction is gradually increased gathering of internal heat effect; After iodine, temperature control is comparatively difficult, it is easy to causing interior temperature too high, product is mixed and disorderly. Needing a large amount of sodium hydride of cancellation that adds water after this step reaction, so operation has certain danger. This step document yield relatively low (60%), when feather weight is amplified, yield only can maintain 40��45%. It is thus desirable to a kind of efficient synthesis, adapt to amplify the demand produced.
