A process for preparing a compound of formula (I):
- ##STR10## wherein n is 2 or 3;
- which process comprises reducing a compound of formula (II):
- ##STR11## wherein R.sup.1 is hydrogen or C.sub.1-4 alkyl and n is 2 or 3;
- by catalytic hydrogenation in the presence of a rhodium catalyst, provided that the yield of the undo isomer is about 82% or greater.
