Procedure

500 mg of the compound of step 2 of Example 25 was dissolved in 10 ml of methylene chloride, 3.5 ml of trifluoroacetic acid (hereinafter referred to as TFA) was added, then the resultant mixture was agitated at room temperature for 30 minutes. This was concentrated, then an aqueous solution of 10% sodium hydroxide was added and extraction was performed with chloroform. The organic layer was washed by saturated saline and was dried with anhydrous magnesium sulfate. This chloroform was concentrated to obtain the above-referenced compound in an amount of 260 mg (yield of 87%).
