実験手順

A mixture of (S)-7-(2-hydroxy-2-methylpropyl)-7-phenyl-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)-1,3-oxazepan-2-one (20 mg, 0.04 mmol), 1-cyclopropyl-4-iodopyridin-2(1H)-one (10 mg, 0.04 mmol), Pd(PPh3)4 (5 mg), and Na2CO3 (43 mg, 0.36 mmol) in toluene/EtOH/H2O (3 mL/2 mL/2 mL) was stirred under N2 at 100° C. for 2 h. The reaction mixture was diluted with water (5 mL), and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated to give the crude product, which was purified by preparative-HPLC to give (S)-3-((S)-1-(4-(1-cyclopropyl-2-oxo-1,2-dihydropyridin-4-yl)phenyl)ethyl)-7-(2-hydroxy-2-methylpropyl)-7-phenyl-1,3-oxazepan-2-one (8 mg, yield 40%) LC-MS Method 4 tR=1.166 min, m/z=443.1; 1H NMR (CDCl3) d 0.85 (m, 5H), 1.10 (m, 6H), 1.43 (m, 1H), 1.52 (d, 3H), 2.18 (m, 2H), 2.20 (d, 1H), 2.36 (d, 1H), 2.79 (m, 1H), 3.12-3.35 (m, 2H), 4.00 (s, 1H), 5.59 (m, 1H), 6.30 (d, 1H), 6.70 (d, 1H), 7.18-7.32 (m, 6H), 7.45 (m, 4H)
