To provide an excellent agent for preventing or treating dementia and schizophrenia based on serotonin 5-HT
5A
receptor regulating action, it was found that a tetrahydroisoquinoline derivative characterized by a structure in which an acylguanidino group binds to a N atom of a tetrahydroisoquinoline ring or the like, and a cyclic group binds to an unsaturated ring has a potent 5-HT
5A
receptor regulating action and an excellent pharmacological action based on the regulating action and also discovered that the tetrahydroisoquinoline derivative is useful as an agent for treating or preventing dementia, schizophrenia, and the like, whereby the present invention has been completed.

A series of fluorine substituted methoxyphenylalkyl amides were prepared with different orientations of the fluorine and methoxy groups with respect to the alkylamide sidechain and with alkyl sides of differing lengths (n = 1–3). β-Dimethyl and α-methyl derivatives were also synthesised. The compounds were tested as melatonin agonists and antagonists using the pigment aggregation of Xenopus melanophores
