PROBLEM TO BE SOLVED: To provide novel cycloalkylamines and their salts for treatment of neurological disorders.SOLUTION: Phenyl-substituted cyclohexylamine derivatives represented by the specified formula and a method for their synthesis and characterization are disclosed. (In the formula, n and s are 1; A is H, alkyl, or the like; X is OR5, where R5 is H, alkyl or the like; Y and Z are halogen; R1 and R2 are H; and R3 and R4 are H, alkyl or the like.) Exemplary compounds inhibit reuptake of endogenous monoamines, such as dopamine, serotonin and norepinephrine and modulate one or more monoamine transporter.

PROBLEM TO BE SOLVED: To provide a crystal composed of a compound usable as a synthetic intermediate for (2R)-2-propyloctanoic acid and an amine. SOLUTION: The invention provides a crystal composed of (2S)-2-propenyloctanoic acid or (2S)-2-propynyloctanoic acid and an amine, keeping the pharmacological effect of (2R)-2-propyloctanoic acid and usable as a synthetic intermediate for a solid medicinal preparation for oral administration. The crystal gives (2R)-2-propyloctaoic acid having excellent handling property and strong pharmacological activity in high optical purity and chemical yield. COPYRIGHT: (C)2007,JPO&INPIT
