The present invention relates to a new path to synthesize crystalline Tafamidis polymorphs starting from a Tafamidis acetic acid adduct. In addition, this invention relates to a process to synthesize Tafamidis (2-(3,5-dichlorophenyl)-1,3-benzoxazole- 6-carboxylic acid * (2R,3R,4R,5S)-6-(methyl-amino)-hexane-1,2,3,4,5-pentol), new Tafamidis crystalline polymorphs, a pharmaceutical compositions comprising the new crystalline polymorphs and to the therapeutic use of such new polymorphs.
本发明涉及一种从Tafamidis醋酸加合物出发合成结晶Tafamidis多晶形态的新途径。此外,本发明涉及一种合成Tafamidis(2-(3,5-二氯苯基)-1,3-苯并咪唑-6-羧酸*(2R,3R,4R,5S)-6-(甲基氨基)-己烷-1,2,3,4,5-五醇)的方法,新的Tafamidis结晶多晶形态,包含这些新结晶多晶形态的药物组合物以及这些新多晶形态的治疗用途。
