Reaction Steps

To a solution of (S)—N-(1-azabicyclo[2.2.2]oct-3-yl)-2-cyclobutylbenzoxazole-4-carboxamide (226 mg, 0.69 mmol) in methanol (1.0 mL) was added a solution of HCl in diethyl ether (1 N, 0.8 mL, 0.8 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-cyclobutylbenzoxazole-4-carboxamide hydrochloride (151 mg, 60%) as a white solid: 1H NMR (500 MHz, CDCl3) δ 12.68 (br s, 1H), 9.61 (d, J=7.0 Hz, 1H), 8.13 (dd, J=7.8, 1.0 Hz, 1H), 7.62 (dd, J=8.0, 0.9 Hz, 1H), 7.44 (t, J=7.8 Hz, 1H), 4.68-4.62 (m, 1H), 3.90-3.75 (m, 2H), 3.50-3.23 (m, 5H), 2.60-2.50 (m, 5H), 2.40-2.30 (m, 1H), 2.25-1.95 (m, 5H); MS (ESI+) m/z 326 (M+H); HPLC >99% (AUC), tR=11.60 min.
