Reaction Steps

A solution of compound (19) (0.047 g) in TFA was stirred at room temperature for 3 hours. The solvent was distilled off, and chloroform was added to the residue. The reaction solution was neutralized with an aqueous sodium bicarbonate solution and partitioned into organic and aqueous layers. The organic layer was washed with brine and then dried over anhydrous sodium sulfate. The solvent was distilled off, and diethyl ether was added to the residue. The deposit was filtrated to obtain compound (20) (0.022 g, yield: 60%) as a white solid.
