On February 26, 2015, Blaquiere, Nicole; Burch, Jason; Castanedo, Georgette; Feng, Jianwen A.; Hu, Baihua; Lin, Xingyu; Staben, Steven; Wu, Guosheng; Yuen, Po-Wai published a patent.Quality Control of Methyl 6-amino-2-chloropyrimidine-4-carboxylate The title of the patent was Alkynyl alcohols as NIK kinase inhibitors and their preparation. And the patent contained the following:
The invention relates to compounds of formula I and pharmaceutical compositions thereof are useful in the treatment of diseases and disorders in which undesired or over-activation of NF-kB signaling is observed Compounds of formula I wherein ring A is monocycle and bicycle; A1 is N and CR1; A2 is N, NR2 and CR2; A3 is N, NR3 and CR3; A4 is N and CH; provided that one, two or three of A1 – A4 are N; one of A5 – A8 is N and the remaining are CR6 or all A5 – A8 are CR6; R1 is H, halo, OH, amino, C1-3 alkyl, etc.; R2 is H, OH, amino, C1-6 alkyl, etc.; R3 is H, (un)substituted C1-6 alkyl, C1-6 alkoxy, etc.; R1R2 or R2R3 can be taken together to form a C3-7 cycloalkyl, Ph and 3- to 11-membered heterocyclyl; R4 is C1-6 alkyl, CH2F and CH2OH; R5 is (un)substituted 3- to 11-membered heterocycle; R4R5 can be taken together to form (un)substituted C3-11 cycloalkyl and 3- to 11-membered heterocyclyl; each R6 is independently H, F, Cl, NH2, OH, etc.; and stereoisomers, and salts thereof, are claimed. Example compound II was prepared by cross-coupling of 2-chloropyrimidine-4-carboxamide with potassium (S)-trifluoro(3-((3-hydroxy-1-methyl-2-oxopyrrolidin-3-yl)ethynyl)phenyl)borate. The invention compounds were evaluated for their NIK inhibitory activity (data given). The experimental process involved the reaction of Methyl 6-amino-2-chloropyrimidine-4-carboxylate(cas: 944129-00-4).Quality Control of Methyl 6-amino-2-chloropyrimidine-4-carboxylate
