Reaction Steps

To a solution of the amide from Step B (120 mg, 0.31 mmol) in methanol (1.0 mL) was added a solution of HCl in diethyl ether (1 N, 0.93 mL, 0.93 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 N-(9-methyl-9-azabicyclo[3.3.1]non-6-amino-2-phenylbenzoxazole-4-carboxamide dihydrochloride (54 mg, 38%) as a yellow solid: 1H NMR (500 MHz, DMSO-d6) δ 10.48 (br s, 0.4H), 9.69 (br s, 0.6H), 9.16 (d, J=5.8 Hz, 0.6H), 8.88 (d, J=6.9 Hz, 0.4H), 8.23-8.15 (m, 2H), 7.70-7.60 (m, 3H), 7.55-7.50 (m, 1H), 7.36 (s, 1H), 4.90-4.35 (m, 4H), 3.70-3.65 (m, 1.4H), 3.60-3.55 (m, 0.6H), 2.90-2.80 (m, 4H), 2.75-2.60 (m, 2H), 2.40-2.10 (m, 3H), 1.95-1.82 (m, 2H), 1.60-1.50 (m, 2H); MS (ESI+) m/z 391 (M+H); HPLC>99% (AUC), tR=11.49 min.
