Procedure

A mixture of tert-butyl trans-3-methyl-4-((3-(5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)isoquinolin-1-yl)oxy)pyrrolidine-1-carboxylate (0.640 g, 1.555 mmol) and HCl in 1,4-dioxane (3.8 mL, 15.55 mmol) was stirred for 30 minutes, forming a mustard colored precipitate. The precipitate was filtered, washed with diethyl ether, and dried to give an HCl salt of the title compound (0.550 g, quantitative yield). 1H NMR (500 MHz, DMSO-d6) δ ppm 1.19 (d, 3H), 2.68-2.74 (m, 1H), 3.03 (dd, 1H), 3.27-3.60 (m, 3H), 3.86 (dd, 1H), 5.73-5.85 (m, 1H), 7.69 (t, 1H), 7.78-7.90 (m, 1H), 8.02 (s, 1H), 8.04 (d, 1H), 8.21-8.30 (m, 1H), 9.48 (br s, 1H), 9.67 (br s, 1H), 11.8 (s, 0.5H), 12.01 (s, 0.5H); ESI-MS m/z [M+H]+ 312.6.
