Reaction Steps

N-(8-Methyl-8-azabicyclo[3.2.1]oct-3-yl)-6-chloro-2-phenylbenzoxazole-4-carboxamide was prepared from 6-chloro-2-phenyl-benzoxazole-4-carboxylic acid and 3-amino-8-methyl-8-azabicyclo[3.2.1]octane using the method outlined in Step C of Example 7. This compound was obtained in 20% yield as a white solid: mp 187-190° C.; 1H NMR (500 MHz, CDCl3) δ 9.44 (d, J=7.5 Hz, 1H), 8.26 (d, J=7.1 Hz, 2H), 8.21 (d, J=2.0 Hz, 1H), 7.72 (d, J=2.0 Hz, 1H), 7.65-7.47 (m, 3H), 4.46 (q, J=7.2 Hz, 1H), 3.25 (br s, 1H), 2.38 (m, 5H), 2.26 (m, 4H), 1.84 (d, J=14.3 Hz, 2H), 2.15 (m, 1H), 2.04 (m, 1H), 1.78-1.60 (m, 3H); MS (APCI) m/z 397 [M+H]+
