Claim 6:
7. The method according to claim 1, wherein
R4 is H or C1-C4 alkyl optionally substituted by one or more halogen atoms;
R5 is C1-C4 alkoxy optionally substituted by one or more halogen atoms; —(CH2)m—NR17R18, —(CH2)m—OR′; or —(C0-C4 alkyl)-3 to 14 membered heterocyclic group, wherein the heterocyclic group contains at least one heteroatom selected from N, O and S, wherein the aryl heterocyclyl groups is optionally substituted by one or more Z substituents;
R6 is C1-C4 alkyl optionally substituted by one or more halogen atoms; C1-C4 alkoxy optionally substituted by one or more halogen atoms; or —(C0-C4 alkyl)-C6-C14 aryl wherein the aryl is optionally substituted by one or more Z substituents; or
R4 and R6 together with the carbon atoms to which they are bound form a 3 to 6 membered carbocyclic ring system; or
R5 and R6 together with the carbon atoms to which they are bound form a 5 to 8 membered heterocyclic ring system containing one or more heteroatoms selected from N, O and S, wherein the ring system is optionally substituted by one or more Z substituents;
m is 0 or 1;
R17 and R18 are each independently H or C1-C8 alkyl optionally substituted by one or more halogen atoms.
