The present invention relates to a new crystal of triazaspiroÄ5.5Üundecane derivatives. The crystal of a non-solvate of (3R)-1-butyl-2,5-dioxo-3-Ä(1R)-1-hydroxy-1-cyclohexylmethylÜ-9-Ä4-(4-carboxyphenyloxy)phenylmethylÜ-1,4,9-triazaspiroÄ5.5Üundecane hydrochloride have safety as drug substance, and have possibility to supply at large scale. And the crystal have an antagonistic activity against the interaction between chemokine and chemokine receptor, therefore, it is useful for manufacture of an agent for treating and/or preventing diseases such as various inflammatory diseases, asthma, atopic dermatitis, nettle rash, allergy disease, nephritis, nephropathy, hepatitis, arthritis, chronic rheumatoid arthritis, autoimmune disease, transplanted organ rejection reactions, acquired immunodeficiency syndrome and the like. |
