wherein:
X represents a bond, a double bond, a triple bond, a methylene group optionally substituted by one or two groups selected from a C1-6 alkyl group, a hydroxy group and a C1-4 alcoxy group;
a carbonyl group, an oxygen atom, a sulfur atom, a sulfonyl group, a sulfoxide group or a nitrogen atom being optionally substituted by a C1-6 alkyl group;
R1 represents a 2, 3 or 4-pyridyl group optionally substituted by a C1-4 alkyl group, C1-4 alkoxy group or a halogen atom;
R2 represents a C1-6 alkyl group, a C1-2 perhalogenated alkyl group, a C1-3 halogenated alkyl group, a benzyl group, a phenyl ring, a pyridyl ring, an indole ring, a pyrrole ring, a thiophene ring, a furan ring or an imidazole ring, the benzyl group and the rings being optionally substituted by 1 to 3 substituents selected from a C1-6 alkyl group, a halogen atom, a C1-2 perhalogenated alkyl group, a C1-3 halogenated alkyl group, a hydroxyl group, a C1-4 alkoxy group, a nitro, a cyano, an amino, a C1-6 monoalkylamino group or a C2-10 dialkylamino group;
and n represents 0 to 3.
