Versuchsvorschrift

The product from Example 87A was dissolved in methylene chloride (5 mL) and treated with trifluoroacetic acid (2 mL) at room temperature for 1 hour. Then the reaction mixture was concentrated, partitioned between methylene chloride and an aqueous solution of sodium bicarbonate. The organic layer was separated, dried over magnesium sulfate, and concentrated to yield the title compound. MS (ESI+) m/z 391 (M+H)+.
