## Claims

### Claim 1

A compound of the Formula (IV)
wherein
R1 and R2 independently represent H, C1-C4 alkyl, or either of R1 or R2 taken together with R3 represent a 4- to 6-membered saturated ring, or R1 taken together with R2 represent a 3- to 6-membered saturated ring optionally substituted with an O or a N atom;
R3 represents C1-C4 alkyl or R3 taken together with either of R1 or R2 represent a 4- to 6-membered saturated ring;
R4 represents C1-C4 alkyl or C1-C4 haloalkyl; and
R6 represents H or C1-C4 alkyl.

### Claim 2 (depends on 1)

A compound of claim 1 in which R4 represents CF3.
