Two new stable non stoichiomeric crystalline solvate forms of Eluxadoline with 4-methylpentan-2-one or methyl terf-butylether are described as well as the process for the production of the same. The solvate form with 4-methylpentan-2-one is defined as "Eluxadoline form gamma" whereas the solvate with methyl terfbutylether is defined as "Eluxadoline form delta". Form gamma may be obtained by slurrying Eluxadoline amorphous form in 4-methylpentan-2-one; form delta may be obtained by slurrying Eluxadoline form gamma in methyl terf-butylether.
介绍了两种新的稳定的非化学计量结晶溶剂化物形式的Eluxadoline,其中一种是与4-甲基戊酮或甲基叔丁基醚结晶的形式,同时还介绍了它们的生产过程。用4-甲基戊酮溶剂的溶剂化物形式被定义为“Eluxadoline γ形”,而用甲基叔丁基醚的溶剂化物形式被定义为“Eluxadoline δ形”。γ形可以通过在4-甲基戊酮中搅拌Eluxadoline非晶态形式来获得;δ形可以通过在甲基叔丁基醚中搅拌Eluxadoline γ形来获得。
