    • There is disclosed a method of converting gabapenting hydrochloride substantially free of inorganic salts to gabapenting form II. The method comprises the steps of: (1) obtaining gabapentin hydrochloride that is substantially free of inorganic salts; (2) mixing a solution of the gabapenting hydrochloride with an additional amine in a first solvent so as to obtain a precipitate comprising gabapenting; and then (3) recovering gabapentin form II from the precipitate. The precipitated gabapentin is a novel polymorphic form of gabapentin possessing a crystalline structure characterized by novel sets of peaks in the powder X-ray diffraction pattern and in the FTIR spectra. This newly disclosed polymorph of gabapentin is characterized herein as gabapentin form III. The recovery step may comprise, for example, one of two alternative methods, slurrying the gabapentin form II in methanol, and then filtering the suspension to obtain gabapentin form II, or solubilizing the gabapentin form III in methanol with heating by reflux, and then cooling the solution to obtain gabapentin form II by crystallization.
    • 公开了一种将基本上不含无机盐的盐酸氢化盐转化为耙状II的方法。 该方法包括以下步骤:(1)获得基本上不含无机盐的盐酸加巴喷丁; (2)在第一溶剂中将加巴喷丁盐酸盐溶液与另外的胺混合,以获得包含加砂的沉淀物; 然后(3)从沉淀物中回收加巴喷丁II型。 沉淀的加巴喷丁是一种具有特征在于粉末X射线衍射图和FTIR光谱中新颖的峰组的加巴喷丁的新型多晶型物。 这种新公开的加巴喷丁多晶型物在本文中被表征为加巴喷丁形式III。 回收步骤可以包括例如两种替代方法之一,将加巴喷丁II型在甲醇中制浆,然后过滤悬浮液以获得形式II的加巴喷丁,或者通过回流加热将加巴喷丁形式III溶解在甲醇中,然后冷却 通过结晶获得形式II的加巴喷丁的溶液。
