The present invention relates to salts, processes, and process intermediates useful in the preparation of (R)-2-(9-chloro-7-(4-isopropoxy-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetic acid of Formula (Ia), salts, and crystalline forms thereof. The compound (R)-2-(9-chloro-7-(4-isopropoxy-3-(trifluoromethyl)benzyloxy)-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-yl)acetic acid has been identified as an S1P1 receptor modulator that is useful in the treatment of S1P1 receptor-associated disorders, for example, diseases and disorders mediated by lymphocytes, transplant rejection, autoimmune diseases and disorders, inflammatory diseases and disorders (e.g., acute and chronic inflammatory conditions), cancer, and conditions eases characterized by an underlying defect in vascular integrity or that are associated with angiogenesis such as may be pathologic (e.g., as may occur in inflammation, tumor development, and atherosclerosis).
本发明涉及盐、过程和过程中间体,用于制备式(Ia)的(R)-2-(9-氯-7-(4-异丙氧基-3-(三氟甲基)苯基氧基)-2,3-二氢-1H-吡咯并[1,2-a]吲哚-1-基)乙酸、其盐和结晶形式。化合物(R)-2-(9-氯-7-(4-异丙氧基-3-(三氟甲基)苯基氧基)-2,3-二氢-1H-吡咯并[1,2-a]吲哚-1-基)乙酸已被确认为S1P1受体调节剂,可用于治疗S1P1受体相关的疾病和疾病,例如由淋巴细胞介导的疾病和疾病、移植排斥、自身免疫性疾病和疾病、炎症性疾病和疾病(例如急性和慢性炎症性疾病)、癌症以及表现为血管完整性基础缺陷或与血管生成相关的情况,例如可能是病理性的(例如可能发生在炎症、肿瘤发展和动脉硬化中)。
