Abstract
Abstract 2-OR-4-trifluoromethylbenzoic acid wherein R is H or acyl. The compounds are useful in the treatment of pathological cardiovascular conditions, particularly in the prophylaxis of the thromboembolic diseases. The compounds are made by reacting m-trifluoromethyl phenol with potassium carbonate and carbon dioxide at an elevated temperature and pressure and, if desired, acetylating the 2-OH compound thus obtained or reacting it with a phosphonating agent. The invention also embraces pharmaceutical compositions in which the compounds constitute the effective agent and a method of treatment.
