Procedure

5.435 g (16.9 mmole) of the compound (1) synthesized in (i) was dissolved in 15 ml of chloroform, to which 10 ml of hydrochloric acid-saturated methanol was added, and the mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated under reduced pressure, and 50 ml of 1 N sodium hydroxide aqueous solution was added to the resultant crude product, followed by extraction with chloroform. The organic phase was dried with anhydrous potassium carbonate, and the solvent was evaporated off under reduced pressure, to give 3.72 g of the desired compound (2) (100%, colorless oil).
