Reaction Steps

In a vial, 6-(4-(cyclopropylamino)furo[3,2-d]pyrimidin-2-ylamino)-N,N-dimethyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazole-3-carboxamide (0.94 g, 0.19 mmol, prepared using E.2 from Preparation #AI.1 with dimethylamine) and an aqueous solution of HCl (6 N, 0.401 mL, 2.41 mmol) in DCE (4 mL) were added. The mixture was heated at about 70° C. for about 15 h. The mixture was concentrated under reduced pressure and 1,4-dioxane (4 mL) and NH4OH (0.956 mL, 7.36 mmol) were added. The mixture was heated at about 75° C. for about 3 h, concentrated under reduced pressure and the residue was suspended in MeOH (1 mL) and filtered. The filtrate was purified by column chromatography eluting with 35 to 85% of 10% MeOH in DCM/DCM (12 g silica gel) to give 6-(4-(cyclopropylamino)furo[3,2-d]pyrimidin-2-ylamino)-N,N-dimethyl-1H-indazole-3-carboxamide (0.029 g, 42%): LC/MS (Table 2 Method c) Rt=1.52 min.; MS m/z: 378 (M+H)+.
