-
Paragraph 0072, (2016/12/22)
PROBLEM TO BE SOLVED: To provide a method of producing a pyridine compound of formula (1) represented by 2-cyano-3-ethylthiopyridine. SOLUTION: A method of producing a pyridine compound represented by formula (1) comprises the step for a reaction between a compound represented by formula (4) and a compound represented by formula (5), wherein R2-R4 are H or the like; R1 is a chain hydrocarbon group or the like; and M is an alkali metal atom.

A useful and rapid access to libraries of N-arylbenzo[b]thieno[3,2-d] pyrimidin-4-amines and their pyrido and pyrazino analogues was designed and optimized for the first time via microwave-accelerated condensation and Dimroth rearrangement of the starting anilines with N′-(2-cyanoaryl)-N,N- dimethylformimidamides obtained by reaction of thiophene precursors with dimethylformamide dimethylacetal. The inhibitory potency of the final products against five protein kinases (CDK5/p25, CK1δ/ε, GSK3α/β, DYRK1A and CLK1) was estimated. N-arylpyrido[3′,2′:4,5]thieno[3,2-d] pyrimidin-4-amine series of compounds (4a-j) turned out to be particularly promising for the development of new pharmacological inhibitors of CK1 and CLK1 kinases.
