Paragraph 0095, (2015/07/02)
The present invention relates to a N2,N4-bis(4-(piperazine-1-yl)phenyl)pirimidine-2,4-diamine derivative or a pharmaceutically acceptable salt thereof, and to a composition containing same as an active ingredient for preventing or treating cancer. Since the compound according to the present invention has good effects in inhibiting the activities of anaplastic lymphoma kinase (ALK) and activated Cdc42-associated kinase (ACK1), the compound can have improved therapeutic effects against cancer cells having ALK fusion proteins such as EML4-ALK and NPM-ALK and is expected to be effective in preventing the recurrence of cancer. Therefore, the compound can be effectively used as a composition for preventing or treating cancer.

A practical and highly regioselective aromatic nucleophilic substitution reaction for the substrate 2,4-difluoronitrobenzene is demonstrated with various O/S/N-nucleophiles. Solvent screens substantiate the role of a nonpolar solvent in ortho-selective nucleophilic substitution through a six-membered polar transition state.

[Bmim]PF6 and BF4 ionic liquids as novel and recyclable reaction media for aromatic amination
Yadav,Reddy,Basak,Venkat Narsaiah
, p. 2217 - 2220 (2007/10/03)
Activated aryl halides undergo smooth nucleophilic substitution reactions with secondary amines in 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim]PF6) or 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) ionic liquids (ILs) at room temperature to afford the corresponding arylamines in excellent yields under mild and neutral conditions.
