Procedure

A suspension of Tigecycline was prepared by mixing a solid Tigecycline sample and acetonitrile in amounts as shown in Table A. The mixture was than stirred for 1 hour at room temperature before 5 N hydrochloric acid was added in amounts corresponding to Table A. After stirring for about 20 hours the solid was filtered off and dried at room temperature under vacuum to obtain crystalline form A of Tigecycline hydrochloride.
