Reaction Steps

A flask was charged with N4-cyclopropyl-N2-(4-fluoro-3-methyl-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-6-yl)furo[3,2-d]pyrimidine-2,4-diamine (0.19 g, 0.45 mmol, prepared using B from Preparation #A.1 with Preparation #AN.1) and 4 M HCl in 1,4-dioxane (2 mL). The mixture was stirred at about 50° C. for about 2 h, cooled to rt, concentrated under reduced pressure and purified by reverse phase HPLC (Table 2, Method o) to give N4-cyclopropyl-N2-(4-methyl-1H-indazol-6-yl)furo[3,2-d]pyrimidine-2,4-diamine (0.030, 20%): LC/MS (Table 2, Method h) Rt=1.85 min; MS m/z: 321 (M+H)+.
