is a C?1-6#191 alkyl group optionally substituted by a C?3-10#191 cycloalkyl group, R
2
is a C?2-6#191 alkyl group, R
3
is a hydrogen atom, a C?1-6#191 alkyl group or a halogen atom, and X is —OR
6
or —NR
4
R
5
wherein R
4
and R
6
are each independently a hydrogen atom, an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group, R
5
is an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted hydroxy group, or R
4
and R
5
optionally form, together with the adjacent nitrogen atom, an optionally substituted nitrogen-containing heterocycle, or a salt thereof.
