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 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、用于制备(R)-2-(9-氯-7-(4-异丙氧基-3-(三氟甲基)苄氧基)-2,3-二氢-1H-吡咯并[1,2-a]吲哚-1-基)乙酸(Ia式)的过程和过程中间体,以及其盐和结晶形式。已鉴定出化合物(R)-2-(9-氯-7-(4-异丙氧基-3-(三氟甲基)苄氧基)-2,3-二氢-1H-吡咯并[1,2-a]吲哚-1-基)乙酸为一种S1P1受体调节剂,可用于治疗S1P1受体相关疾病,例如由淋巴细胞介导的疾病和障碍、移植排斥、自身免疫疾病和障碍、炎症性疾病和障碍(如急性和慢性炎症症状)、癌症,以及具有血管完整性缺陷或与血管生成相关的疾病和情况,如可能是病理的(如可能发生在炎症、肿瘤发展和动脉粥样硬化中)。
