Procedure
To a solution of the compound prepared in Example 3(106) (80 mg) in methanol (1 ml) was added 2N aqueous solution of sodium hydroxide (0.5 ml). The reaction mixture was stirred for 2.5 hours at room temperature. To the reaction mixture on ice bath was added 1N hydrochloric acid until the pH of the solution was below 5, then it was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, concentrated. The obtained residue was purified by column chromatography on silica gel (dichloromethane:methanol=9:1). To a solution of the obtained compound in ethyl acetate was added 4N hydrogen chloride in ethyl acetate solution. The reaction mixture was concentrated to give the title compound (64 mg) having the following physical data.
