Inhibition of Src kinase activity by 7-ethynyl-4-phenylamino-3-quinolinecarbonitriles: Identification of SKS-927

Of a series of 7-ethynyl-3-quinolinecarbonitriles, the most potent Src inhibitory activity was observed with 4-[(2,4-dichloro-5-methoxyphenyl)amino]-6-methoxy-7-[4-(4-methylpiperazi n-1-yl)but-1-ynyl]-3-quinolinecarbonitrile (SKS-927). Variation of the so

4 [(2,4-DICHLORO-5-METHOXYPHENYL)AMINO]-6-ALKOXY-7-ETHYNYL-3-QUINOLINECARBONITRILES FOR THE TREATMENT OF ISCHEMIC INJURY

This invention relates to compounds of the formula (I): wherein: R is methyl or ethyl; R' and R" are independently alkyl of 1 to 3 carbon atoms, or R' and R", taken together with the nitrogen to which they are attached, can form a 5 or 6 membered saturate

Process for preparation of 4-amino-3-quinolinecarbonitriles

This invention discloses a process for the preparation of a 4-amino-3-quinolinecarbonitrile comprising combining an amine compound with a cyanoacetic acid and an acid catalyst to yield a cyanoacetamide; condensing the cyanoacetamide with an optionally up to tetra-substituted aniline in an alcoholic solvent and a trialkylorthoformate to yield a 3-amino-2-cyanoacrylamide; combining the 3-amino-2-cyanoacrylamide with phosphorus oxychloride in acetonitrile, butyronitrile, toluene or xylene, optionally in the presence of a catalyst to yield a 4-amino-3-quinolinecarbonitrile and also discloses a process for the preparation of a 7-amino-thieno[3,2-b]pyridine-6-carbonitrile comprising combining a disubstituted 3-amino thiophene with a cyanoacetamide and trialkylorthoformate in an alcoholic solvent to obtain a 3-amino-2-cyanoacrylamide; and combining the 3-amino-2-cyanoacrylamide with phosphorus oxychloride and acetonitrile, butyronitrile, toluene or xylene, optionally in the presence of a catalyst to yield a 7-amino-thieno[3,2-b]pyridine-6-carbonitrile and also discloses a process for the preparation of a 4-amino-3-quinolinecarbonitrile by combining an amine compound with a cyanoacetic acid and a peptide coupling reagent to obtain a suspension; filtering the suspension to yield a cyanoacetamide; condensing the cyanoacetamide with an optionally up to tetra-substituted aniline, an alcoholic solvent, and triethylorthoformate to yield a 3-amino-2-cyanoacrylamide; and combining the 3-amino-2-cyanoacrylamide with phosphorus oxychloride to yield a 4-amino-3-quinolinecarbonitrile.
