Sodium Carbonate → Methyl2-(4-(4-(5-aminopyridin-2-yl)phenyl)-2-oxabicyclo[2.2.2]octan-1-yl)acetate

Participants

Reaction Steps

To a microwave vial containing methyl 2-(4-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-2-oxabicyclo[2.2.2]octan-1-yl)acetate (100 mg, 0.26 mmol), 6-bromopyridin-3-amine (49 mg, 0.28 mmol) and Pd2(PPh3)4 (60 mg, 0.05 mmol) was added 1,4-dioxane (1.3 ml) at room temperature. 2N sodium carbonate (0.39 ml, 0.78 mmol) was added and the mixture was subjected to microwave radiation at 120° C. for 50 minutes. The resulting mixture was concentrated to dryness and taken up in EtOAc, the slurry was dried over sodium sulfate and filtered through a pad of celite. The filtrate was concentrated and purified by column chromatography to afford the title compound (120 mg, 65% yield). LC/MS, ESI-MS(+): 353.4, RT: 1.12 (Condition E).
