実験手順

A 100-mL single-neck round-bottomed flask equipped with a reflux condenser was charged with 199b (500 mg, 1.5 mmol), {3-[(acetyloxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatri-cyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (1200 mg, 3.0 mmol), Pd(dppf)Cl2 (65 mg, 0.075 mmol), K3PO4 (650 mg, 3.0 mmol), sodium acetate trihydrate (420 mg, 3.0 mmol), water (6 drops), and acetonitrile (20 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 100° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 199f (240 mg, 40%) as a yellow-brown solid. MS-ESI: [M+H]+ 593.4.
