A process is described for the preparation of compounds of the formula (1)
(and their salts and hydrates) in which:
W is alkylene
X is cis or trans-CH=CH-;
Y is a saturated heterocyclic amino group having 5-8 ring members; and
R2 is C3-6 alkenyl (optionally substituted), C1-12 alkyl, or substituted or unsubstituted phenylalkyl, thienylalkyl, furanylalkyl, biphenylalkyl or naphthylalkyl.
The process comprises hydrolysing an ester of the acid (1).
