Abstract
The present invention relates to a process for the preparation of an oligomeric compound, comprising introduction of a lipophilic capping group to an unreacted reactive group, suitable for chain elongation, of a not elongated oligomeric compound intended to be elongated in a preceeding chain-elongation step, by reacting a lipophilic capping compound with said unreacted reactive group, which lipophilic capping group is not removable under the applied conditions of the synthesis and work-up of the oligomeric compound; and which not elongated oligomeric compound capped with said lipophilic capping group can be separated from said oligomeric compound on a hydrophobic stationary phase.
