Reaction Steps

To a solution of 1-(5-bromopyridin-2-yloxy)-2-methylpropan-2-ol (30 mg, 0.122 mmol) in DME (6 mL) was added Pd(PPh3)4 (10 mg) under nitrogen. The mixture was stirred for 1 h at rt. A solution of (S)-6-(2-hydroxy-2-methylpropyl)-6-phenyl-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)-1,3-oxazinan-2-one (58.4 mg, 0.122 mmol) in EtOH (2 mL) and satd aq NaHCO3 (2 mL) were added. The mixture was stirred at 100° C. for 2 h, quenched with water, and extracted with EtOAc (3×10 mL). The combined organic layer was dried over anhydrous Na2SO4, concentrated, and purified by preparative TLC (1:1 PE/EtOAc) and HPLC to afford the title compound (7.6 mg, 12.1%). 1H NMR (CDCl3): δ 8.23 (d, 1H), 7.72 (q, 1H), 7.74-6.68 (m, 10H), 5.70 (m, 1H), 4.24 (s, 2H), 3.43 (s, 1H), 2.85 (m, 1H), 2.40 (m, 1H), 2.27-2.14 (m, 5H), 1.54 (d, 3H), 1.33-1.29 (d, 3H), 1.18-1.12 (d, 3H).
