Procedure

A suspension of (S)-(−)-aminoquinuclidine dihydrochloride (55 mg, 0.275 mmol) in dichloromethane (1 mL) as treated with triethylamine (53 μL, 0.55 mmol) followed by 5-(5-Trifluoromethyl-4-methyl-isoxazol-3-yl)-thiophene-2-carbonyl chloride (74 mg, 0.25 mmol) and the reaction mixture allowed to stir for 20 hr. After this time, the reaction mixture was evaporated and the residue partitioned between EtOAc (5 mL) and a 1 N HCl solution (10 mL). The aqueous portion was then basified to pH ˜10-12 with a 1N NaOH solution. The aqueous portion was then extracted with EtOAc (10 mL) which was then washed with a brine solution (10 mL), dried over MgSO4, filtered, and evaporated in vacuo to afford product as a colorless solid (38 mg, 40%). 1H NMR (CDCl3) 1.50-1.62 (m, 1H), 1.70-1.88 (m, 3H), 2.08-2.12 (m, 2H), 2.37 (d, J=1.3, 3H), 2.72-3.10 (m, 5H), 3.44 (ddd, J=14.0, 9.7, 2.2, 1H), 4.14-4.22 (m, 1H), 6.56 (br d, J=7.0, 1H), 7.49 (d, J=4.0, 1H), 7.56 (d, J=4.0, 1H). 19F NMR −63.13. LC/MS 4.63 min, [M+1]+ 386.
