NOVEL CRYSTAL OF SUBSTITUTED PHENYLALKANOIC ACID AND METHOD OF PRODUCING THE SAME

摘要

[PROBLEMS] To provide 3-[3-amino-4-(indan-2-yloxy)-5-(1-methyl-1H-indazol -5-yl)phenyl]propionic acid, methyl 3-[4-(indan-2-yloxy)-3-(1-methyl-1H-inda zol-5-yl)-5-nitrophenyl]propionate, or methyl 3-[3-amino-4-(indan-2-yloxy)-5 -(1-methyl-1H-indazol-5-yl)phenyl]propionate in a more preferred form for us e as a medicine; and an improved method therefor. [MEANS FOR SOLVING PROBLEM S] Provided are crystals of a compound which is 3-[3-amino-4-(indan-2-yloxy) -5-(1-methyl-1H-indazol-5-yl)phenyl]propionic acid, methyl 3-[4-(indan-2-ylo xy)-3-(1-methyl-1H-indazol-5-yl)-5-nitrophenyl]-propionate, or methyl 3-[3-a mino-4-(indan-2-yloxy)-5-(1-methyl-1H-indazol-5-yl)phenyl]propionate. Also p rovided is a process for producing the crystals.
