Reaction Steps

Potash powder (0.07 g) is added to a solution of 5a (0.798 g, 1.24 mmol) in 8.75 mL of toluene/i-PrOH (6/1). The mixture is heated in a reverse-flow boiler for 1 h. After cooling, the potash is filtered and the solvents are evaporated. The raw product is purified by silica gel column chromatography (heptane/CH2Cl2 90:10) to yield 0.632 g (87%) of 5b.
