Reaction Steps

A mixture of 7b (0.14 g, 2.1 eq), 6a (0.1 g, 0.3 mmol) and potassium carbonate (0.1 g, 2.2 eq) in 1 mL of DMA was heated up to 90° C. for 48 h then cooled down to room temperature and diluted with DCM (2 mL) and brine (2 mL). The layers were separated and the aqueous extracted with DCM (2×2 mL). The combined extracts were washed with brine (2×50 mL), dried over magnesium sulfate, filtered and evaporated. The residue was diluted with acetonitrile and purified on preparative HPLC to afford 7c.
