Abstract
1. Process for obtaining esters of apovincamºnico acid, characterized in that the vincamine is hydrolyzed in alkaline free vincamºnico acid, which is dehydrated by the action of a dehydrating energetic, to originate apovincamºnico acid, whose treatment with a chlorinating agent allows obtain the corresponding acid chloride, already capable of reacting with aliphatic or aromatic alcohols to give the esters of apovincamºnic acid.
