Quinazoline derivatives of formula (I); for use in the treatment of proliferative diseases such as cancer and in the preparation of medicaments for use in the treatment of proliferative diseases, and to process for their preparation, as well as pharmaceutical compositions containing them as active ingredient.
The invention concerns a compound of the Formula (I) wherein m is 0-2 and each R
1
is a group such as hydroxy, halogeno, trifluoromethyl heterocyclyl and heterocyclyloxy; R
2
is halogeno, trifluoromethyl or (1-6C)alkyl; R
3
is hydrogen, halogeno or (1-6C)alkyl; and R
4
is (3-6C)cycloalkyl; or pharmaceutically-acceptable salts thereof; processes for their preparation, pharmaceutical compositions containing them and their use in the treatment of diseases or medical conditions mediated by cytokines.
