Procedure

N-(1-Azabicyclo[2.2.2]oct-3-yl)-2-(4-methoxyphenyl)benzoxazole-7-carboxamide was prepared from 2-(4-methoxyphenyl)benzoxazole-7-carboxylic acid and 3-aminoquinuclidine dihydrochloride using the method outlined in Step C of Example 14. This compound was obtained in 24% yield as a white solid: mp 166-167° C.; 1H NMR (500 MHz, CD3OD) δ 8.20 (dd, J=7.0, 2.0 Hz, 2H), 7.86 (d, J=7.9 Hz, 1H), 7.84 (d, J=7.9 Hz, 1H), 7.49 (t, J=7.9 Hz, 1H), 7.14 (dd, J=1.9, 7.0 Hz, 2H), 4.26 (m, 1H), 3.91 (s, 3H), 3.42 (m, 1H), 3.02 (m, 1H), 2.92 (m, 3H), 2.83 (m, 1H), 2.16 (d, J=3.1 Hz, 1H), 2.07 (m, 1H), 1.84 (m, 2H), 1.68 (m, 1H); MS (ESI) m/z 378 [M+H]+.
