Reaction Steps

To a suspension of (R)-tert-butyl 3-(6-bromo-4-(tert-butoxycarbonylamino)-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (119) (100 mg, 0.15 mmol), oxazole (52 mg, 0.75 mmol), t-BuOK (35 mg, 0.3 mmol) in dioxane (4 mL) was added tetrakis (36 mg, 0.03 mmol). The resulting mixture was purged with N2 (2×) before heated to 100° C. under N2 atmosphere for 30 hrs. The mixture was cooled down to r.t and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, 0 to 50% EA in PE) to afford (R)-tert-butyl 3-(4-amino-6-(oxazol-2-yl)-5-(4-phenoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)pyrrolidine-1-carboxylate (123) (30 mg, 42% yield) as a white solid. LC-MS (ESI): m/z (M+1) 539.1.
