Patent ID: 7982053

Claim:
A compound according to Formula (I): wherein: R1 is —N(OH)—CHO; R2 is selected from: 1) C 1 -C 6 -alkyl, 2) C 3 -C 7 -cycloalkyl, 3) aryl, or 4) heteroaryl, wherein: C 1 -C 6 -alkyl is optionally substituted by one to three R6 groups; each C 3 -C 7 -cycloalkyl, aryl, and heteroaryl as defined above optionally are substituted by one to three R7 groups; R3 and R4 are joined together to form a pyrrolidinyl ring or a pyrrolidinyl ring optionally substituted with one or two C1-C3 alkyl groups; 1) —C(O)R8, 2) —C(O)OR8, or 3) —C(O)NR8R9; wherein: R6 as defined above independently is selected from: 1) OH, 2) CF 3 , 3) —NR9R9, 4) cyano, 5) OC 1 -C 3 -alkyl, 6) phenyl, 7) heteroaryl, 8) heterocycloalkyl, 9) —NHC(O)OC 1 -C 6 -alkyl, or 10) —NHCOH; R7 as defined above independently is selected from: 1) OH, 2) halo, 3) cyano, 4) nitro, 5) —NR9R9, 6) CF 3 , 7) —NHC(O)CH 3 , 8) —OCH 3 , 9) C 1 -C 6 -alkyl, 10) heteroaryl, or 11) heterocycloalkyl; R8 as defined above independently is selected from: 1) C 1 -C 6 -alkyl, 2) C 2 -C 6 -alkenyl, 3) C 3 -C 7 -cycloalkyl, 4) phenyl, 5) heteroaryl or 6) heterocycloalkyl, wherein: C 1 -C 6 -alkyl is optionally substituted by one to three R6 groups; C 3 -C 7 -cycloalkyl, phenyl, and heteroaryl are each optionally substituted by one to three R7 groups; or heterocycloalkyl is optionally substituted by one to three R10 groups; each R9 as defined above independently is selected from: 1) H or 2) C 1 -C 6 -alkyl; R10 as defined above independently is selected from 1) OH, 2) C 1 -C 6 -alkyl, 3) phenyl, 4) NH 2 ; 5) —C(O)OC 1 -C 6 -alkyl; or a pharmaceutically acceptable salt thereof.
