摘要

PURPOSE: N-phenyl-2-pyrimidine-amine derivatives and a process for the preparation thereof are provided, which compounds have improved anti-cancer activity, so that it can be useful for treatment of cancers such as lung cancer, stomach cancer, colon cancer, pancreas cancer, liver cancer, prostate cancer, breast cancer, leukemia, blood cancer, brain cancer, bladder cancer, rectal cancer and cervix cancer. CONSTITUTION: The N-phenyl-2-pyrimidine-amine derivatives represented by formula (1) and pharmaceutically acceptable salts thereof are provided, wherein R1 is 3-pyridyl or 4-pyridyl; R2 and R3 are independently hydrogen or lower alkyl; R6 or R7 are substituted with a radical of formula (2); X is oxygen or NH; n is 0 or 1; and R9 is C5 to C10 aliphatic group, optionally substituted monocyclic radical which contains 1 to 3 hetero atoms selected from nitrogen, oxygen and sulfur, and 5- to 7-membered cyclic ring, optionally benzene ring fused bi- or tri-cyclic radical, or lower alkyl substituted piperazinyl or homopiperazinyl, wherein R4, R5, R7 and R8 are simultaneously hydrogen or one or two of them are independently halogen, lower alkyl or lower alkoxy when the radical of formula (2) is substituted with R6, and one or two of R4, R5, R6 and R8 are independently halogen, lower alkyl or lower alkoxy when the radical of formula (2) is substituted with R7, provided that one or more of R4, R5, R7 and R8, or one or more of R4, R5, R6 and R8 is halogen when R6 or R7 are substituted with the radical of formula (2) of which R9 is 4-methylpiperazine and n is 0.
