    • Disclosed are 2-amino-6-fluoro-N-(pyridin-3-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide derivatives and analogues useful as inhibitors of ATR kinase as represented by the general formula (I); or a pharmaceutically acceptable salt thereof, wherein: R1 is–C(J1)2CN or halo; R9 is H; each J1 is independently H, methyl or ethyl; or two occurrences of J1, together with the carbon atom to which they are attached, form a 3-4 membered optionally substituted carbocyclic ring; R2 is H; halo; -CN; NH2; or a methyl or ethyl group optionally substituted with fluoro; or a C1-3aliphatic chain wherein up to two methylene units of the aliphatic chain are optionally replaced with -O-, -NR-, -C(O)-, or –S(O)n; R3 is H; halo; alkyl optionally substituted with 1-3 occurrences of halo; cycloalkyl; heterocyclyl; -CN; or an aliphatic chain wherein up to two methylene units of the aliphatic chain are optionally replaced with -O-, -NR-, -C(O)-, or –S(O)n; R4 is Q1 or an aliphatic chain wherein up to four methylene units of the aliphatic chain are optionally replaced with -O-, -NR-, -C(O)-, or -S(O)n-; R4 is optionally substituted with 0-5 occurrences of JQ; or R3 and R4, taken together with the atoms to which they are bound, form a 5-6 membered aromatic or non-aromatic ring having 0-2 heteroatoms selected from oxygen, nitrogen and sulfur; the ring formed by R3 and R4 is optionally substituted with 0-3 occurrences of JZ; provided that the compound is not 2-amino-6-fluoro-N-[5-fluoro-4-[4-[4-(oxetan-3-yl)piperazine-1-carbonyl]-1-piperidyl]-3-pyridyl]pyrazolo[1,5-a]pyrimidine-3-carboxamide. Also disclosed are the compounds selected from 2-amino-6-fluoro-N-(5-fluoro-4-(4-(4-(3-methyloxetan-3-yl)piperazine-1-carbonyl)piperidin-1-yl)pyridin-3-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide; 4-(1-(3-(2-amino-6-fluoropyrazolo[1,5-a]pyrimidine-3-carboxamido)-5-fluoropyridin-4-yl)piperidine-4-carbonyl)-1-methylpiperazine 1-oxide; 2-amino-6-fluoro-N-(5-fluoro-4-(4-(4-(1-methylazetidin-3-yl)piperazine-1-carbonyl)piperidin-1-yl)pyridin-3-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide; and 2-amino-6-fluoro-N-(5-fluoro-4-(1-methyl-1H-imidazol-5-yl)pyridin-3-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide. There is also disclosed a pharmaceutical composition having properties of inhibitor of ATR protein kinase for treating cancer comprising an effective amount of a compound as defined above and a pharmaceutically acceptable carrier.
