A solution of 3 methoxy-10-(3 chloro-2-methylpropyl)phenthia2ine (9.65 grams) and 4-hydroxypiperidine (6.1 grams) in xylene (lOcc) is heated under reflux for 5 hours. After cooling the mixture is diluted with ether (60 cc) and the basic compounds are extracted by agitation with water (30 cc) and 4N hydrochloric acid (20 cc). The aqueous acid phase is made alkaline with 4N sodium hydroxide solution (23 cc) and the liberated base is extracted with ether. The ethereal solution is washed with water (60 cc) and dried over sodium sulfate. Finally the solvent is distilled off on a water-bath.
