Reaction Steps

To a solution of (S)—N-(1-azabicyclo[2.2.2]oct-3-yl)-2-(2-methylcyclopropyl)benzoxazole-4-carboxamide (149 mg, 0.45 mmol) in methanol (0.5 mL) was added a solution of HCl in diethyl ether (1 N, 0.92 mL, 0.92 mmol) at room temperature slowly. The reaction mixture was diluted with diethyl ether. The resulting solid was filtered and washed with diethyl ether to afford (S)—N-(1-azabicyclo[2.2.2]oct-3-yl)-2-(2-methylcyclopropyl)benzoxazole-4-carboxamide hydrochloride (82 mg, 51%) as a white solid and as a mixture of diastereomers: 1H NMR (500 MHz, DMSO-d6) δ 12.68 (br s, 1H), 9.51 (br s, 1H), 8.12 (d, J=8.0 Hz, 1H), 7.68 (d, J=8.0 Hz, 1H), 7.38 (t, J=7.9 Hz, 1H), 4.69-4.58 (m, 1H), 3.80-3.70 (m, 1H), 3.50-3.20 (m, 5H), 2.60-2.50 (m, 1H), 2.40-2.35 (m, 1H), 2.25-1.95 (m, 4H), 1.65-1.60 (m, 1H), 1.50-1.42 (m, 1H), 1.35-1.30 (m, 2H), 1.17-1.10 (m, 2H); MS (ESI+) m/z 326 (M+H); HPLC 98.9% (AUC), tR=11.59 min.
