Ring-substituted 2-amino 1,2,3,4-tetra-hydronaphthalenes and 3-aminochromanes.

摘要

The present invention provides novel ring-substituted 2-amino-1,2,3,4-tetrahydronaphthalenes which exhibit binding activity at the serotonin 1A receptor and 3-aminochromane intermediates. The pharmaceutical compounds have the formula <CHEM> in which R is C1-C4 alkyl, allyl, or cyclopropylmethyl; R1 is hydrogen, C1-C4 alkyl, allyl, cyclopropylmethyl, or aryl(C1-C4-alkyl); R2 is hydrogen or methyl; X is -CH2- or -O-; R3 is C1-C8 alkyl, aryl, substituted aryl, aryl(C1-C4-alkyl), substituted aryl(C1-C4 alkyl), or C5-C7 cycloalkyl; n is 0, 1, or 2; and pharmaceutically acceptable acid addition salts thereof.
