The present invention provides an isomer of N
1
-(5-chloropyridin-2-yl)-N
2
-((1S,2R,4S)-4-[(dimethylamino)carbonyl]-2-[(5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)carbonyl]amino}cyclohexyl)ethanediamide represented by formula (II) or a salt thereof, or a solvate thereof. Such an isomer or a salt thereof, or a solvate thereof is useful as a standard in a test for inspecting impurities in a pharmaceutical composition containing a compound represented by formula (II) or a salt thereof, or a hydrate thereof. The present invention also relates to a substantially pure compound that is useful as a preventive and/or therapeutic drug for thrombotic diseases, and a pharmaceutical composition containing the substantially pure compound.
本发明提供了一种N1-(5-氯吡啶-2-基)-N2-((1S,2R,4S)-4-[(二甲基氨基)羰基]-2-[(5-甲基-4,5,6,7-四氢噻唑并[5,4-c]吡啶-2-基)羰基]氨基}环己基)乙二酰胺的异构体,其化学式表示为(II),或其盐或溶剂化合物。这种异构体或其盐,或其溶剂化合物可用作检测含有化学式(II)或其盐,或其水合物的药物组合物中杂质的标准。本发明还涉及一种用作预防和/或治疗血栓性疾病的纯度较高的化合物,以及含有该纯度较高化合物的药物组合物。
