Abstract

The present invention provides 4,6-disubstituted pyrimidine compound useful as kinase inhibitors, pharmaceutically acceptable compositions thereof, and methods of using the same.

Claims (163)

1. A compound of formula I:

or a pharmaceutically acceptable salt thereof, wherein:

Ring A is an optionally substituted group selected from phenyl, an 8-10 membered bicyclic partially unsaturated or aryl ring, a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaryl ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur;

Ring B is phenyl, a 5-6 membered heteroaryl ring having 1-3 heteroatoms independently selected from N, O or S, a 5-6 membered saturated heterocyclic ring having 1-2 heteroatoms independently selected from N, O or S, or an 8-10 membered bicyclic partially unsaturated or aryl ring having 1-3 heteroatoms independently selected from N, O or S;

R 1 is a warhead group -L-Y selected from the following (a), (b), (c), (h), (i), (l), (m), (n), (o), and (p) combinations of -L- and -Y:

(a) L is a bivalent C 2-8 straight or branched, hydrocarbon chain wherein L has at least one double bond and one or two additional methylene units of L are optionally and independently replaced by —NRC(O)—, —C(O)NR—, —N(R)SO 2 —, —SO 2 N(R)—, —S—, —S(O)—, —SO 2 —, —OC(O)—, —C(O)O—, cyclopropylene, —O—, —N(R)—, or —C(O)—; and Y is hydrogen or C 1-6 aliphatic optionally substituted with oxo, halogen, NO 2 , or CN; or

(b) L is a bivalent C 2-8 straight or branched, hydrocarbon chain wherein L has at least one double bond and at least one methylene unit of L is replaced by —C(O)—, —NRC(O)—, —C(O)NR—, —N(R)SO 2 —, —SO 2 N(R)—, —S—, —S(O)—, —SO 2 —, —OC(O)—, or —C(O)O—, and one or two additional methylene units of L are optionally and independently replaced by cyclopropylene, —O—, —N(R)—, or —C(O)—; and Y is hydrogen or C 1-6 aliphatic optionally substituted with oxo, halogen, NO 2 , or CN; or

(c) L is a bivalent C 2-8 straight or branched, hydrocarbon chain wherein L has at least one double bond and at least one methylene unit of L is replaced by —C(O)—, and one or two additional methylene units of L are optionally and independently replaced by cyclopropylene, —O—, —N(R)—, or —C(O)—; and Y is hydrogen or C 1-6 aliphatic optionally substituted with oxo, halogen, NO 2 , or CN; or

(h) L is a bivalent C 2-8 straight or branched, hydrocarbon chain wherein L has at least one alkylidenyl double bond and at least one methylene unit of L is replaced by —C(O)—, —NRC(O)—, —C(O)NR—, —N(R)SO 2 —, —SO 2 N(R)—, —S—, —S(O)—, —SO 2 —, —OC(O)—, or —C(O)O—, and one or two additional methylene units of L are optionally and independently replaced by cyclopropylene, —O—, —N(R)—, or —C(O)—; and Y is hydrogen or C 1-6 aliphatic optionally substituted with oxo, halogen, NO 2 , or CN; or

(i) L is a bivalent C 2-8 straight or branched, hydrocarbon chain wherein L has at least one triple bond and one or two additional methylene units of L are optionally and independently replaced by —NRC(O)—, —C(O)NR—, —N(R)SO 2 —, —SO 2 N(R)—, —S—, —S(O)—, —SO 2 —, —OC(O)—, or —C(O)O—, and Y is hydrogen or C 1-6 aliphatic optionally substituted with oxo, halogen, NO 2 , or CN; or

(l) L is a covalent bond and Y is selected from:
