(j) other than when R
2
is in the 3-position in combination with R
3

3
is fluoro;
(k) R
2
is 2-pyridinylmethoxy and R
3

(2) at least one of R
1
, R
2
and R
3
is selected from benzyloxy, 3-chlorobenzyloxy and 2-pyridinylmethoxy and when at least one of R
1

2
and R
3
is not benzyloxy, 3-chlorobenzyloxy or 2-pyridinylmethoxy, each of the others is independently selected from H, halogen, and C
2
-C
4
alkynyl, with the proviso that when one of R
1
, R
2
and R
3
is benzyloxy or 2-pyridinylmethoxy, the other two of R
1
, R
2
and R
3
are not H; or
(3) two of R
1
, R
2
and R
3
, together with the carbon atoms to which they are attached, form 1-(3-fluorobenzyl)-1H-pyrazole; and the other is selected from H, halogen and C
2
-C
4
alkynyl.
Also provided are reductive prodrugs, comprising a kinase inhibitor as defined above and a reductive trigger linked directly or indirectly to a nitrogen of the kinase inhibitor. Further provided are pharmaceutical compositions, comprising the kinase inhibitors or the prodrugs, and the use of such compositions in therapy, in particular for treating cancer.
