secondary C-Hbonds, which are adjacent to an oxygen or nitrogen atom on one side, and benzylic or adjacent to a carbonyl group on the other side. A variety of valuable fused heterocycles were obtained from easily accessible ortho-bromophenol and aniline precursors. The second C-H bond cleavage was successfully replaced with carbonyl insertion to generate other types of C(sp3 )-C(sp3 ) bonds.
Provided is a new serotonin-reuptake inhibitor that exhibits affinity for serotonin-1A receptors. Said serotonin-reuptake inhibitor is a compound represented by formula (1) or a pharmacologically acceptable salt thereof. In the formula, R
1
represents a hydrogen atom, a 2-hydroxyethyl group, or a 2-methoxyethyl group. R
2
represents one of the following bonded to a methylene group which is bonded to a piperidine ring: a chlorine atom bonded in a p-position; a bromine atom bonded in a p-position; a methyl group bonded in a p-position; a chlorine atom bonded in an m-position; or a bromine atom bonded in an m-position. Either Y
1
represents a hydrogen atom and Y
2
represents a hydrogen atom or a hydroxyl group, or Y
1
and Y
2
together represent an oxo group. Z represents a group represented by one of the following formulas: formula (3-1-1), formula (3-1-2), formula (3-2-1), formula (3-2-2), formula (3-3-1), formula (3-3-2), formula (3-4-1), or formula (3-4-2). However, if R
1
represents a 2-hydroxyethyl group or a 2-methoxyethyl group and Y
1
and Y
2
both simultaneously represent hydrogen atoms, then Z represents a group represented by one of the following formulas: formula (3-1-2), formula (3-2-1), formula (3-2-2), formula (3-3-1), formula (3-3-2), formula (3-4-1), or formula (3-4-2).
Disclosed are compounds of the formula:
where variables Z, X, R

are defined herein. Compounds disclosed herein are inhibitors of the beta-secretase enzyme and are therefore useful in the treatment of Alzheimer's disease and other diseases characterized by deposition of A beta peptide in a mammal.
Disclosed is a benzylpiperizine compound represented by formula (1) or a pharmaceutically acceptable salt thereof, which is useful as a medicinal agent such as an antidepressant agent. (In the formula (1), R
1
represents a hydrogen atom or a methyl group; R
2
is a group bound in a p- or m-position relative to a methylene group and represents a chlorine atom bound in a p-position, a bromine atom bound in a p-position, a methyl group bound in a p-position, a chlorine atom bound in a m-position or a bromine atom bound to in a m-position; X represents a methylene or an oxygen atom; and n represents an integer of 1 to 3.)
