Procedure

1-Perhydro-2H-pyran-2-yl-3-[3-(3-piperidylpropanoylamino)phenyl]-1H-indazole-5-carboxamide was suspended in 20 mL of toluene and HCl gas was bubbled through for 15 min. The reaction mixture became gummy and was stirred at room temperature overnight. The supernatant solution was decanted and the residue was purified by preparatory HPLC. (0.017 g, 7% yield over 2 steps): 1H NMR (DMSO d6) δ 13.48 (s, 1H), 10.38 (s, 1H), 8.62 (s, 1H), 8.1 (s, 1H), 7.94 (dd, 1H), 7.94 (dd, 1H), 7.73 (d, 1H), 7.62 (d, 1H), 7.48 (t, 1H), 7.36 (br s, 1H), 2.65 (m, 2H), 2.5 (m, 2H), 2.4 (br s, 4H), 1.52 (m, 4H), 1.40 (m, 2H); ES-MS (m/z) 392 [M+H]+.
