実験手順
A mixture of above 1,2,4-oxadiazole (7-E) (115.2 mg, 0.238 mmol) and the trifluoroacetic acid salt of methylamine (1.73 g, 11.9 mmol) in a 2M solution of methylamine in methanol (4 mL) was heated at 150° C. in a sealed tube for 48 h. The mixture was then concentrated, and the residue was taken up in dichloromethane, washed with saturated sodium bicarbonate aqueous solution. The organics were concentrated and the residue was purified using reverse-phase HPLC with TFA- buffered acetonitrile/water (40-80%) as eluent. The fractions containing the product were combined, neutralized with saturated sodium bicarbonate aqueous solution and lyophilized from acetonitrile/water to provide 3-(4-fluorophenyl)-5-(4-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}bicyclo[2.2.2]oct-1-yl)-1,2,4-oxadiazole (7-F). 1HNMR (CDCl3) δ 2.25-2.35 (m, 12H), 3.53 (s, 3H), 7.21 (t, J=8.7 Hz, 2H), 7.54 (m, 1H), 7.73 (m, 2H), 7.88 (m, 1H), 8.13 (m, 2H). ESI-MS m/z (M+H) 498.2.
