실험 절차

To a room temperature slurry of 0.391 g of 50% sodium hydride in 20 ml of dry tetrahydrofuran is added, via cannula, 1.27 g of product from Example 121 in 30 ml of dry tetrahydrofuran. The reaction is stirred at room temperature for 1.5 hours. Two and one half grams of product from Example 20 in 30 ml of dry tetrahydrofuran is added via cannula. The reaction is stirred at room temperature for 20 hours followed by heating at reflux temperature for 2 hours. The cooled reaction is poured into half saturated sodium chloride and extracted with methylene chloride. The combined organic layers are washed with saturated sodium chloride, dried and concentrated in vacuo. The residue is purified by chromatography (silica gel: 40% ethyl acetate/hexane) to give 1.22 g of the desired product as colorless crystals.
