Reaction Steps

To a solution of tert-butyl (1S,4S)-5-{-4-[4-amino-5-(2-benzyl-2H-indazol-6-yl)pyrrolo[2,1-f][1,2,4]triazin-7-yl]butyl}-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate in MeOH (1 mL) was added 4M HCl in dioxane (0.5 mL). The mixture was stirred at rt for 2 h. Additional 4M HCl in dioxane (0.5 mL) was added and the mixture continued to stir at rt for 16 h. The mixture was concentrated and the residue was partitioned between saturated, aqueous NaHCO3 (20 mL) and EtOAc (20 mL). The layers were separated and the organic phase was washed with brine, dried (Na2SO4) and concentrated. The residue was purified by preparative HPLC using a gradient elution from 15% to 50% acetonitrile in water to obtain 36 mg (62%) of the desired product. 1H NMR (400 MHz, DMSO-d6) δ 8.54 (s, 1 H), 7.88 (s, 1 H), 7.79 (d, 1 H), 7.57 (s, 1 H), 7.28-7.39 (m, 5 H), 7.13 (d, 1 H), 6.58 (s, 1 H), 5.64 (s, 2 H), 3.51 (s, 1 H), 3.25-3.47 (m, 2 H), 2.97 (d, 1 H), 2.87 (t, 2 H), 2.73 (dd, 1 H), 2.66 (dd, 2 H), 2.37-2.45 (m, 1 H), 2.33 (d, 1 H), 1.59-1.77 (m, 3 H), 1.35-1.52 (m, 3 H); ES-MS m/z 493.27 [M+H]+, HPLC RT (min) 1.89.
