The present invention provides a process for the preparation of a compound of formula I [Chemical formula should be inserted here. Please see paper copy] in which a compound of formula II [Chemical formula should be inserted here. Please see paper copy] in which R is H or OR represents a protecting group for a carboxylic hydroxy group is reacted with a compound of formula III C6H13X wherein X is a leaving group, in the presence of a base in the presence of an inert solvent at a temperature in the range -25°C to 150°C and optionally, when OR represents a protecting group, removal of the protecting group.
