A process to isolate a compound of Formula (2a) or a salt or solvate thereof, comprising a) reacting a mixture of diastereoisomers of Formulae (2a, 2b) with a basic heterocyclic-aldehyde compound and an optically active amine in the presence of a base; and b) separating the compound of Formula (2a) from the product of step a) by acid extraction. The compound of Formula (2a) may be produced with an enantiomeric excess of 98%. Compounds of Formula (2a) are useful intermediates in a process to prepare a bicyclic γ - amino tetrazole derivative of Formula (I) which finds utility in treating neuropathic pain and disorders of the central nervous system.
一种分离化合物公式(2a)或其盐或溶剂化物的方法,包括a)在碱的存在下,将公式(2a,2b)的对映异构体混合物与一种碱性杂环醛化合物和一种手性活性胺反应;和b)通过酸提取从步骤a)的产物中分离出公式(2a)的化合物。公式(2a)的化合物可具有98%的对映体过量。公式(2a)的化合物是制备公式(I)的双环γ-氨基四唑衍生物的有用中间体,在治疗神经病理性疼痛和中枢神经系统障碍方面具有实用性。
