The present invention relates to processes, and process intermediates useful in the preparation of (1aS,5aS)-2-(4-oxy-pyrazin-2-yl)-1a,2,5,5a-tetrahydro-1H-2,3-diaza-cyclopropa[a]pentalene-4-carboxylic acid ((S)-1-hydroxymethyl-2,2-dimethyl-propyl)-amide (Compound 1) and crystalline forms thereof. The compound (1aS,5aS)-2-(4-oxy-pyrazin-2-yl)-1a,2,5,5a-tetrahydro-1H-2,3-diaza-cyclopropa[a]pentalene-4-carboxylic acid ((S)-1-hydroxymethyl-2,2-dimethyl-propyl)-amide has been identified as a modulator of the cannabinoid 2 (CB2) receptor and useful in the treatment of CB2 receptor-mediated disorders, for example, pain, disorders of the immune system (such as, autoimmune disorders, type 1 hypersensitivity and allergic response, conditions associated with CNS inflammation, conditions associated with vascular inflammation, and other disorders associated with aberrant or unwanted immune response), bone and joint diseases (such as, osteoporosis and arthritis), eye disease, cough, cancer, and regenerative medicine. The present invention further provides pharmaceutical compositions comprising Compound 1 and the use of the pharmaceutical compositions for the treatment of CB2 receptor-mediated disorders.
本发明涉及用于制备(1aS,5aS)-2-(4-氧基吡嗪-2-基)-1a,2,5,5a-四氢-1H-2,3-二氮杂-环丙[a]戊二烯-4-羧酸((S)-1-羟甲基-2,2-二甲基-丙基)-酰胺(化合物1)及其结晶形式的过程和过程中间体。已确定该化合物(1aS,5aS)-2-(4-氧基吡嗪-2-基)-1a,2,5,5a-四氢-1H-2,3-二氮杂-环丙[a]戊二烯-4-羧酸((S)-1-羟甲基-2,2-二甲基-丙基)-酰胺为大麻素2(CB2)受体调节剂,并在治疗CB2受体介导的疾病中有用,例如疼痛、免疫系统疾病(如自身免疫疾病、1型超敏反应和过敏反应、与中枢神经系统炎症相关的疾病、与血管炎症相关的疾病以及其他与异常或不需要的免疫反应相关的疾病)、骨骼和关节疾病(如骨质疏松和关节炎)、眼疾、咳嗽、癌症和再生医学。本发明还提供包含化合物1的药物组合物以及用于治疗CB2受体介导的疾病的药物组合物的用途。
