Claim:
A compound of formula (I) or a pharmaceutically acceptable salt thereof, wherein R 1 is selected from alkoxy, hydroxy, and —NHSO 2 R 7 ; R 2a and R 2b are independently selected from hydrogen and methyl; R 3 is aryl, R 4 is —OR 8 ; R 5 is hydrogen; R 6 is selected from hydrogen, alkyl, alkoxycarbonyl, alkylaminocarbonyl, alkylcarbonyl, aminocarbonyl, aryloxycarbonyl, cycloalkyloxycarbonyl, dialkylaminocarbonyl, haloalkoxycarbonyl, haloalkyl, haloalkylcarbonyl, heterocyclyloxycarbonyl, and (NR a R b )sulfonyl; R 7 is selected from alkyl, aryl, cycloalkyl, (cycloalkyl)alkyl, dialkylaminocarbonyl, dialkylaminocarbonylalkyl, heterocyclyl, heterocyclylcarbonyl, and —NR a R b ; wherein the cycloalkyl and the cycloalkyl part of the (cycloalkyl)alkyl are optionally substituted with one, two, or three groups independently selected from alkenyl, alkoxy, alkoxyalkyl, alkyl, arylalkyl, arylcarbonyl, cyano, cycloalkenyl, (cycloalkyl)alkyl, halo, haloalkoxy, haloalkyl, and (NR e R f )carbonyl; and wherein R a and R b are independently selected from hydrogen, alkoxy, alkyl, aryl, arylalkyl, cycloalkyl, (cycloalkyl)alkyl, haloalkyl, heterocyclyl, and heterocyclylalkyl; and wherein R e and R f are independently selected from hydrogen, alkyl, aryl, arylalkyl, and heterocyclyl; wherein the aryl, the aryl part of the arylalkyl, and the heterocyclyl are optionally substituted with one or two substituents independently selected from alkoxy, alkyl, and halo; R 8 is alkyl; and Q is a C 5-7 saturated or unsaturated chain, optionally containing one heteroatom selected from O, S(O) m , and NR 9 , wherein m is 0, 1, or 2, and R 9 is selected from hydrogen, alkoxy, alkoxycarbonyl, alkyl, alkylcarbonyl, alkylsulfonyl, aminocarbonyl, arylsulfonyl, cycloalkyl, (cycloalkyl)alkyl, cycloalkyloxy, dialkylaminocarbonyl, dialkylaminocarbonylalkyl, haloalkyl, and heterocyclylcarbonyl.
