Compounds of formula (I):
wherein
X is O, CH2, S or NH, or the moiety X—R1 is hydrogen;
V is CH or N;
R1 is hydrogen, C1-6alkyl, C3-7cycloalkyl, aryl, arylC1-6alkyl, heterocyclyl, heterocyclylC1-6alkyl, heteroaryl, or heteroarylC1-6alkyl any of which except for hydrogen may be optionally substituted;
R2 and R3 independently represent optionally substituted C1-6alkyl, or R2 and R3 together with the carbon atom to which they are attached form an optionally substituted C3-7cycloalkyl or C3-7cycloalkenyl ring; or R2 and R3 together with the carbon atom to which they are attached form an optionally substituted 5 to 7-membered heterocyclyl ring containing up to 3 heteroatoms selected from N, O, S.R4 and R5 independently represent hydrogen, C1-6alkyl, C3-7cycloalkyl, aryl, arylC1-6alkyl, heteroaryl, heteroarylC1-6alkyl, heterocyclyl, or heterocyclylC1-6alkyl, any of which except for hydrogen may be optionally substituted or R4 and R5 together with the nitrogen atom to which they are attached form 4- to 8-membered ring;
Ar is an aryl or heteroaryl ring either of which may be optionally substituted;
one of X1 and X2 is N and the other is NR6, wherein R6 is hydrogen, C1-6alkyl, or arylC1-6alkyl
or pharmaceutically acceptable salts thereof, their use as inhibitors of Raf kinases, and pharmaceutical compositions containing them.
