In methanol; butanone; | The E-2-METHOXY-N- (3- {4- [3-METHYL-4- (6-METHYL-PYRIDIN-3-YLOXY)- PHENYLAMINO]- QUINAZOLIN-6-YL}-ALLYL)-ACETAMIDE edisylate complex was synthesized by dissolving 0.5 equivalents of 1,2 ethanedisulfonic acid in 80: 20 methyl ethyl ketone (MEK)/METHANOL (MEOH) (V/V). The E-2-METHOXY-N- (3- {4- [3-METHYL-4- (6-METHYL-PYRIDIN-3-YLOXY)-PHENYLAMINO]- QUINAZOLIN-6-YL}-ALLYL)-ACETAMIDE free base, prepared according to the method of Example 1,2 or 3 was dissolved in approximately 60: 40 MEK/MeOH (v/v), and added dropwise to the 1,2- ethanedisulfonic acid solution with stirring. Initially, an oil was formed which later crystallized into solid powders. The material was determined to be an anhydrous hemiedisylate by elemental analysis |
