[wherein R
3
represents a di-lower alkylamino group, a morpholino group, a piperidino group, a 2-methyl-piperidino group, or a 2-oxo-pyrrolidinyl group; p represents an integer from 2 to 6];
[wherein, R

represents a lower alkyl group];
m and n each represent an integer from 0 to 3;
the term lower represents a carbon number of 1 to 6; and
the halogen atom represents a fluorine, chlorine or bromine atom] can inhibit endoplasmic reticulum stress to a greater extent as compared to known chemical chaperones. The compound thus can be used suitably as an agent for preventing, ameliorating or treating various diseases that are caused by endoplasmid reticulum stress.
