A new and excellent method is provided to prevent and / or treat diseases related to a type 2 cannabinoid receptor, based on an agonistic action on a type 2 cannabinoid receptor. It was found that a hetero-ring derivative primarily having two substituents, for example, a pyrimidine-5-carboxamide derivative having a substituent amino group at position 2, exhibits a potent agonistic action on a type 2 cannabinoid receptor, and can be an agent for preventing and / or treating diseases related to a type 2 cannabinoid receptor such as inflammatory diseases, pain, and the like, thereby concluding the present invention. |
