3-(4-iodophenoxy)quinuclidine

[0184] 3-Hydroxy quinuclidine (Aldrich, 2.54 g, 20 mmol) in toluene (anhydrous, Aldrich, 50 mL) was treated with 1,4-diiodobenzene (Aldrich, 7.9 g, 24 mmol), CuI (Strem Chemicals, 0.38 g, 2 mmol), and 1,10-phenanthroline (Aldrich, 0.72 g, 4 mmol) and heated at 110° C. for 40 hours. The reaction mixture was allowed to cool to room temperature, diluted with chloroform (100 mL), and washed with water (2×10 mL). The organic phase was concentrated and the title compound was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.20) as an oil (3.7 g, yield, 56%). 1H NMR (MeOH-d4, 300 MHz) δ 1.40-1.56 (m, 1H), 1.64-1.80 (m, 2H), 1.90-2.08 (m, 1H), 2.10-2.21 (m, 1H), 2.60-3.00 (m, 5H), 3.34-3.40 (m, 1H), 4.46 (m, 1H), 6.73 (d, J=8.8 Hz, 2H), 7.56 (d, J=8.8, Hz, 2H), ppm.

[0185] The product of Example 1A (330 mg, 1 mmol) in toluene (8 mL) was treated with 3-amino-phenylboronic acid (Lancaster, 276 mg, 2 mmol), Pd2(dba)3 (Strem Chemicals, 18.3 mg, 0.02 mmol), 1,3-bis(2,6-di-1-propylphenyl)imidazolium chloride, 95%, 26.9 mg, 0.06 mmol), and Na2CO3 (aqueous, 2M, 2 mL, 4 mmol) at 110° C. for 15 hours. The reaction mixture was allowed to cool to room temperature, diluted with ethyl acetate (20 mL), and washed with brine (2×5 mL). The organic phase was concentrated and the title compound was purified by chromatography (SiO2, CH2:Cl2:MeOH:NH3.H2O, 90:10:2, Rf. 0.10) as oil (230 mg, yield, 78%). 1H NMR (MeOH-d4, 300 MHz) δ 1.40-1.53 (m, 1H), 1.62-1.85 (m, 2H), 1.96-2.20 (m, 2H), 2.80-2.94 (m, 5H), 3.28-3.40 (m, 1H), 4.52-4.60 (m, 1H), 6.66 (ddd, J=7.8, 2.3, 1.0 Hz, 1H), 6.89 (ddd, J=7.3, 1.6, 1.0 Hz, 1H), 6.92-6.96 (m, 3H), 7.13 (t, J=7.8, Hz, 1H), 7.48 (dt, J=8.8, 2.1 Hz, 2H) ppm.

Abstract

Compounds of formula (I) wherein A is N or N+—O−; n is 0, 1, or 2; Y is O, S, —NH—, and —N-alkyl-; Ar1 is both 6-membered aromatic rings; Ar2 is 5- or 6-membered aromatic rings with a —NR8R9 group, as defined herein. The compounds are useful in treating conditions or disorders prevented by or ameliorated by α7 nAChR ligands. Also disclosed are pharmaceutical compositions having compounds of formula (I) and methods for using such compounds and compositions.

Description

[0001] This application claims priority to U.S. Provisional Patent Application Ser. No. 60 / 531,877, filed Dec. 22, 2003, which is incorporated herein by reference.TECHNICAL FIELD [0002] The invention relates to 3-quinuclidinyl amino-substituted biaryl derivatives, compositions comprising such compounds, and methods of treating conditions and disorders using such compounds and compositions. DESCRIPTION OF RELATED TECHNOLOGY [0003] Nicotinic acetylcholine receptors (nAChRs) are widely distributed throughout the central (CNS) and peripheral (PNS) nervous systems. Such receptors play an important role in regulating CNS function, particularly by modulating release of a wide range of neurotransmitters, including, but not necessarily limited to acetylcholine, norepinephrine, dopamine, serotonin and GABA. Consequently, nicotinic receptors mediate a very wide range of physiological effects, and have been targeted for therapeutic treatment of disorders relating to cognitive function, learning...
