Reaction Steps

A mixture of 0.28 g of Compound 2B, 0.21 g of Compound 2A and 0.14 g of potassium carbonate was heated at 160° C. for 20 minutes. After cooling to room temperature, the mixture was taken up with 8 mL of chloroform, and inorganic matter was filtered off. The filtrate was evaporated to dryness and purified by flash chromatography (chloroform:methanol 97.5:2.5) to yield 0.32 g (71%) of the title compound. M.p. 92-98° C.
