The invention relates to compounds of formula I:

##STR00001##

and pharmaceutically acceptable salts thereof wherein A, X, R.sup.1, R.sup.4 and n are as defined herein. In addition, the present invention relates to methods of manufacturing and methods of using the compounds of formula I as well as pharmaceutical compositions containing such compounds. The compounds may be useful in treating diseases and conditions mediated by TRPA1, such as pain.

The present invention provides compounds, compositions thereof, and methods of using the same.

The present invention provides compounds, compositions thereof, and methods of using the same.

As a drug substance, a crystal having good physical properties is preferable. However, the crystal form that is most excellent as a drug substance may vary with the compound. In general, it is difficult to predict a crystal form of a drug substance having good physical properties, and it is required to variously examine each compound. Therefore, an object of the present invention is to provide a crystal having good physical properties as a drug substance for a novel compound.

The present invention relates to a crystal of the compound represented by the following formula (I) useful for the treatment of an inflammatory bowel disease.
