合成路线1
该中间体在本合成路线中的序号：(VII)Rociletinib is prepared by condensation of 2,4-dichloro-5-trifluoromethylpyrimidine (I) with N-Boc-1,3-diaminobenzene (II) in the presence of DIEA in BuOH to give the secondary amine (III), which is N-deprotected using TFA in CH2Cl2 yielding the primary amine (IV).Coupling of amine (IV) with acryloyl chloride (V) in CH2Cl2 affords amide (VI), which is condensed with intermediate (VII) by means of TFA in dioxane at 50 °C to provide rociletinib trifluoroacetate (VIII) . Finally, rociletinib trifluoroacetate (VIII) is treated with Na2CO3 in CH2Cl2 , followed by treatment of the obtained free base with HBr.
