实验过程

To a solution of EXAMPLE 34C (0.13 g, 0.43 mmol) in 7:3:2 dimethoxyethane/ethanol/water (3 mL) was added phenyl boronic acid (0.053 g, 0.43 mmol), 1M aqueous sodium carbonate (0.6 mL) and dichlorobis (triphenylphosphine)-palladium (II) (0.015 g, 0.022 mmol). The solution was heated to 160° C. in a CEM microwave @100 W for 20 minutes. The crude material was diluted with ethyl acetate, washed with brine, dried over magnesium sulfate, filtered, and concentrated. Purification by flash chromatography (Analogix 280, gradient elution, 5-75% ethyl acetate/hexane) gave the title compound. MS (ESI) m/e 344.0 (M+H)+.
