The present invention relates to a N2-(2-methoxyphenyl)pyrimidine derivative, a preparation method thereof, and a pharmaceutical composition for the prevention or treatment of cancer comprising the same as an active ingredient. The N2-(2-methoxyphenyl)pyrimidine derivative, the optical isomer thereof, or the pharmaceutically acceptable salt thereof of the present invention is very effective in suppressing anaplastic lymphoma kinase (ALK) activity and as a result it can improve the effectiveness of treatment on cancer cells having anaplastic lymphoma kinase (ALK) fusion proteins such as EML4-ALK and NPM-ALK, so that it can be effectively used as a pharmaceutical composition for preventing or treating cancer.

tertiary amines to oxidatively generate α‐amino radicals is well established, however, primary amines remain challenging because of competitive side reactions. This report describes the site‐selective α‐functionalization of primary amine derivatives through the generation of α‐amino radical intermediates. Employing visible‐light photoredoxcatalysis, primary sulfonamides are coupled with electron‐deficient

method for the remote regioselective alkynylation of unactivated C(sp3)–H bonds in diverse aliphatic amides by photogenerated amidyl radicals has been developed. The site-selectivity is dominated via a 1,5-hydrogenatomtransfer (HAT) process of the amide. Mild reaction conditions and high regioselectivity are demonstrated in this methodology.

Alcohol-anchored sulfamate esters guide the alkylation of tertiary and secondary aliphatic C(3)-H bonds. The transformation proceeds directly from N-H bonds with a catalytic oxidant, a contrast to prior methods which have required preoxidation of the reactive nitrogen center, or employed stoichiometric amounts of strong oxidants to obtain the sulfamyl radical. These sulfamyl radicals template otherwise rare 1,6-hydrogen-atom transfer (HAT) processes via seven-membered ring transition states to enable C(3)-H functionalization during Giese reactions.
