using Cu Kα radiation essentially the same as that provided in FIG. 1” (copied below). (Id. at 19:13-15.) Claim 4 depends from claim 1 and adds the limitation that the Form A crystal has a monoclinic form. (Id. at 19:18-19.) Claim 24 depends from claim 1 and is a product-by-process claim that adds the limitation that Form A is produced by the process of: dissolving (−) hydrochloride of Form B in acetonitrile together with active carbon, heating the solution to the boiling removing the active carbon by filtering, stirring the solution at a temperature 40o C., removing part of the solvent residue by filtering and removing part of the solvent, leaving (−) hydrochloride of Form A to crystalize, redissolving the resulting crystals in acetonitrile, removing insoluble residue by filtering and removing part of the solvent, and leaving (−) hydrochloride of Form A to crystalize. (Id. at 19:38-55.)
