Potassium Carbonate → Ammonium Hydroxide

Participants

Reaction Steps

[(3-Bromo-4-fluorophenyl)methyl]amine hydrochloride (0.795 g, 3.29 mmol), [3-(hydroxymethyl)phenyl]boronic acid (0.5 g, 3.29 mmol), potassium carbonate (2.275 g, 16.5 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.114 g, 0.1 mmol) were combined in dioxane (10 mL) and water (3 mL). The mixture was microwaved at 150° C. for 30 min. The solvents were concentrated and the residue taken up in EtOAc and H2O. The aqueous phase was extracted 2× with EtOAc. The combined organic phases were dried over anhydrous Na2SO4, filtered and concentrated. The residue was purified by CombiFlash on a silica gel column eluted with 0-100% CH2Cl2/CH2Cl2: 20% MeOH: 1% NH4OH to afford the title compound as viscous oil. LC-MS m/z 231.8 (M+H)+, 1.03 min (ret time).
