Benefits of technology

[0041]administering to said subject an effective amount of at least one compound of formula I or pharmaceutically acceptable salt thereof.
[0042]In yet another embodiment, the present invention is directed to methods for treating or preventing a depression disorder in a subject in need thereof, comprising the step of:

Problems solved by technology

Hormonal treatments are very effective at alleviating VMS, but they are not appropriate for all women.
It is well-recognized that VMS are caused by fluctuations of sex steroid levels and can be disruptive and disabling in both males and females.
It is usually accompanied by outbreaks of profuse sweating.
Hot flushes and outbreaks of sweats occurring during the night can cause sleep deprivation.
As many as one-third of these patients will experience persistent and frequent symptoms severe enough to cause significant discomfort and inconvenience.
In addition, hormone replacement therapy is usually not recommended for women or men with or at risk for hormonally sensitive cancers (e.g. breast or prostate cancer).
However, using such treatment is associated with a number of undesired side effects caused by high doses necessary to abate hot flash described herein and known in the related arts.

a) Aldol Reaction

Preparation of Acid Intermediates

[0395]A solution of diisopropylamine (7.87 mL, 56.2 mmol) in dry tetrahydrofuran (50 mL) under nitrogen was cooled to −78° C. and treated dropwise with a solution of n-butyllithium (2.5 M in hexanes, 22 mL, 55.0 mmol). The resulting solution was warmed to 0° C. and stirred for 15 min. The solution was re-cooled to −78° C. and treated, via cannula, with a solution of 3-chlorophenylacetic acid (4.0 g, 23.4 mmol) in tetrahydrofuran (20 mL). The reaction was then allowed to warm to 25° C. where it was stirred for 45 minutes and was then re-cooled to −78° C. A solution of cyclohexanone (3.65 mL, 35.3 mL) in tetrahydrofuran (10 mL) was then added via cannula, and the resulting mixture was stirred at −78° C. for 1.5 h. The reaction was then quenched by the addition of a saturated aqueous solution of ammonium chloride, and the tetrahydrofuran was removed in vacuo. The resulting residue was dissolved in a 2N aqueous solution of sodium hydroxi...

1-[1-(3-chlorophenyl)-2-piperazin-1-ylethyl]cyclohexanol dihydrochloride

[0404]

[0405]Step 1: A solution of (3-chlorophenyl)(1-hydroxycyclohexyl)acetic acid (Reference Example 1-a) (5.4 g, 20.1 mmol), benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate (14.22 g, 32.15 mmol), and tert-butyl 1-piperazinecarboxylate (5.99 g, 32.15 mmol) in methylene chloride (20 mL) was treated with triethylamine (8.4 mL, 60.3 mmol). The reaction was stirred at 25° C. for 16 h, after which time the solvent was removed in vacuo and the product was purified via Biotage Horizon (FLASH 40 M, silica, gradient from 0% EtOAc / hexane to 30% EtOAc / hexane) to yield 7.10 g (81%) tert-butyl 4-[(3-chlorophenyl)(1-hydroxycyclohexyl)acetyl]piperazine-1-carboxylate as a white foam. HRMS: calcd for C23H33ClN2O4, 436.2129; found (ESI_FT), 437.21996.

[0406]Step 2: A solution of 4-[(3-chlorophenyl)(1-hydroxycyclohexyl)acetyl]piperazine-1-carboxylate (200 mg, 0.46 mmol) in dry tetrahydrofuran (3 mL) under ni...

1-[2-(1,4′-bipiperidin-1′-yl)-1-(3-chlorophenyl)ethyl]cyclohexanol dihydrochloride

[0407]

[0408]In an analogous manner to Example 1, step 1 1-[2-(1,4′-bipiperidin-1′-yl)-1-(3-chlorophenyl)-2-oxoethyl]cyclohexanol was prepared from (3-chlorophenyl)(1-hydroxycyclohexyl)acetic acid (Reference Example 1-a) and N-(4-piperidine)piperidine. MS (ESI) m / z 419 / 421 ([M+H]+); HRMS: calcd for C24H35ClN2O2, 418.2387; found (ESI), 419.2451.

[0409]In an analogous manner to Example 1, step 2 1-[2-(1,4′-bipiperidin-1′-yl)-1-(3-chlorophenyl)ethyl]cyclohexanol dihydrochloride was prepared from 1-[2-(1,4′-bipiperidin-1′-yl)-1-(3-chlorophenyl)-2-oxoethyl]cyclohexanol. MS (ESI) m / z 405 / 407 ([M+H]+); HRMS: calcd for C24H37ClN2O.2.00HCl, 476.2128; found (ESI), 405.2664.

Abstract

The present invention is directed to substituted N-heterocycle derivatives, compositions containing these derivatives, and methods of their use for the prevention and treatment of conditions ameliorated by monoamine reuptake including, inter alia, vasomotor symptoms (VMS), sexual dysfunction, gastrointestinal and genitourinary disorders, chronic fatigue syndrome, fibromylagia syndrome, nervous system disorders, and combinations thereof, particularly those conditions selected from the group consisting of major depressive disorder, vasomotor symptoms, stress and urge urinary incontinence, fibromyalgia, pain, diabetic neuropathy, and combinations thereof.
