Dependent claims

An enantiomer of a compound of formula (I):

including a pharmaceutically acceptable salt or an in vivo hydrolysable ester thereof, wherein:
X is selected from —C(CH3)— or —S— provided that when X is —S— then Y is —C(CH3)—;
Y is selected from —C(CH3)— or —O— or —S— provided that when Y is —C(CH3)— then X is not —C(CH3)—;
m is 0 or 1;
R1 is F when m is 1;
R2 and R3 are independently selected from H or C1-3alkyl;
wherein if both R2 and R3 are selected from C1-3alkyl they are identical;
n is 2 or 3;
R4 and R5 are independently selected from H or C1-3alkyl;
Z is optionally substituted phenyl, or optionally substituted benzothiophene wherein the number of optional substituents is 1 or 2 and each is independently selected from F, Cl, Br, CH3 or CH2CH3;
and
“*” represents a chiral center;
wherein said enantiomer is substantially free of the other enantiomer;
and wherein the optical rotation of the enantiomer, when said enantiomer is dissolved at a concentration of 1 mg/ml in methanol, at 20.0° C. measured at 589 nM is (+).
