実験手順

Through a suspension of 3-[3-(2-methoxyacetylamino)phenyl]-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carboxamide in toluene (10 mL), HCl gas was bubbled for 20 min. After 6 hours at room temperature, the reaction was complete. The pH of the reaction mixture was neutralized using a saturated aqueous NaHCO3 solution before the solvent was removed under reduced pressure. The title compound was isolated as a white solid after purification by preparative HPLC (30–100% acetonitrile/water) (0.078 g, 40.5% yield): 1H NMR (CD3OD) δ 8.63 (dd, 1H), 8.19 (t, 1H), 7.94 (dd, 1H), 7.74 (td, 2H), 7.60 (dd, 1H), 7.49 (t, 1H), 4.06 (s, 2H), 3.49 (s, 3H); ES-MS (m/z) 325 [M+H]+.
