Reaction Steps

A mixture of 6-bromo-3-(tert-butyl)-8-phenyl-3,4-dihydro-2H-benzo[e][1,3]oxazine (from Example 42, Step 2) (0.404 g, 1.17 mmol), pyridin-4-ylboronic acid (0.288 g, 2.0 equiv), and potassium carbonate (0.647 g, 4 equiv) in isopropanol (30 mL) and water (6 mL) was purged with nitrogen for 20 minutes. Tetrakis(triphenylphosphine)Pd (0) (88 mg, 6.5 mol %) was added and the resulting mixture was heated at 55° C. for 4 hours. The cooled reaction mixture was concentrated and the resulting residue was purified by column chromatograph to give 3-((tert-butylamino)methyl)-5-(pyridine-4-yl)-[1,1′-biphenyl]-2-ol (0.126 g).
