Abstract
Crystals of a dispiropyrrolidine compound or a salt thereof which inhibits the action of Mdm2 are provided. The present invention provides crystals of (3′R,4′S,5′R)-N-[(3R,6S)-6-carbamoyltetrahydro-2H-pyran-3-yl]-6″-chloro-4′-(2-chloro-3-fluoropyridin-4-yl)-4,4-dimethyl-2″-oxo-1″,2″-dihydrodispiro[cyclohexane-1,2′-pyrrolidine-3′,3″-indole]-5′-carboxamide or a salt thereof which inhibits Mdm2 and has anti-tumor activity. The present invention also provides a medicament comprising the same.
Claims3
A crystal of (3′R,4′S,5′R)-N-[(3R,6S)-6-carbamoyltetrahydro-2H-pyran-3-yl]-6″-chloro-4′-(2-chloro-3-fluoropyridin-4-yl)-4,4-dimethyl-2″-oxo-1″,2″-dihydrodispiro[cyclohexane-1,2′-pyrrolidine-3′,3″-indole]-5′-carboxamide represented by the following formula (1):
- wherein:
- the crystal is a benzenesulfonate salt;
- and
- the crystal has the X-ray diffraction pattern as shown in FIG. 8 as determined by X-ray powder diffraction obtained by copper Kα radiation (wavelength λ=1.54 angstroms).
