Abstract

This application relates to quinazoline derivatives of formula (I), pharmaceutical compositions comprising the compounds of formula (I), and the use of the compounds of formula (I) in the treatment or prevention of a viral infection, of a virus-induced disease, of cancer or of an allergy. In formula (I), R1 is a C3-8alkyl, optionally substituted by one or more substituents independently selected from fluorine, hydroxyl, amino, nitrile, ester, amide, C1-3 alkyl, or C1-3 alkoxy, the carbon of R1 bonded to the amine in the 4-position of the quinazoline is in (R)-configuration, R2 is hydrogen, deuterium, fluorine, chlorine, methyl, methoxy, cyclopropyl, trifluoromethyl, or carboxylic amide, wherein each of methyl, methoxy and cyclopropyl is optionally substituted by one or more substituents independently selected from fluorine and nitrile, R3 is hydrogen or deuterium, R4 is hydrogen, deuterium, fluorine, methyl, carboxylic ester, carboxylic amide, nitrile, cyclopropyl, C4-7 heterocycle, or 5-membered heteroaryl group, wherein each of methyl, cyclopropyl, C4-7 heterocycle and 5-membered heteroaryl group is optionally substituted by one or more substituents independently selected from fluorine, hydroxyl, or methyl, R5 is hydrogen, deuterium, fluorine, chlorine, methyl, or methoxy, provided that at least one of R2, R3, R4 and R5 is not hydrogen.
