摘要：Compounds of formula (I): ##STR1## in which: n represents 1 or 2,< P>

R.sub.1 represents hydrogen or alkyl, benzyl, acetyl, benzoyl, allyl, pyridinecarbonyl,pyridinemethyl, acylaminoalkyl (optionally substituted), pyridineaminocarbonyl,phthalimidoalkyl, thiochromanyloxyalkyl or (benzodioxanyloxy)alkyl,

R.sub. 2, R.sub.3 or R.sub.4, which may be identical or different, represent hydrogen orhalogen or alkyl, alkoxy, hydroxyl, acetyl, aminocarbonyl, aminomethyl, cyano, nitro,amino, phenyl (which may or may not be substituted), furyl, pyridinyl, thienyl or pyridyl, oralternatively, when they are located on adjacent carbons, R.sub.2 and R.sub.3 form, withthe carbon atoms which bear them, a furan or phenyl ring,

< P>the isomers thereof and the addition salts thereof with a pharmaceuticallyacceptable acid, and medicinal products containing the same are useful for the treatmentof diseases requiring a ligand to the 5- HT.sub.2C receptors.
