Reaction Conditions

Reaction Steps

Title compound 455 (0.890 g, 2.81 mmol) and the methyl 4-hydroxybenzoate (0.512 g, 3.37 mmol) were dissolved in acetonitrile (10.0 mL) and the cesium carbonate (1.83 g, 5.62 mmol) was added. The reaction mixture was stirred at 100° C. in a sealed tube for 4 hours. The mixture was cooled down to room temperature and diluted with ethyl acetate. The organic layer was washed with water (2 times) and brine, dried over sodium sulfate, filtered and evaporated. The crude was purified by flash chromatography (30-40% ethyl acetate in hexanes) to afford title compound 456 (355 mg, 32%) as white foam. MS (m/z): 390.3 (M+H).
