The compound of formula (I) binds to a prostaglandin E2 receptor, especially an EP1 subtype receptor, and antagonizes it. It is less affected by protein binding, so it has a satisfactory in vivo activity. Therefore, it is considered to be useful as an analgesic, an antipyretic agent, an agent for the treatment of pollakiuria (frequent urination) and/or lower urinary tract disease syndrome or an antineoplastic agent.
