Procedure
To a solution of the compound prepared in Example 27 (0.045 g, 0.056 mmol) in ethanol (10 mL) was added Pd/C (20% by wt, 0.010 g). The reaction was stirred under an atmosphere of hydrogen (40 psi) at room temperature for 2 h. The reaction mixture was filtered through diatomaceous earth and the filtrate concentrated to afford the title compound (0.03 g, 69%) as a pale green solid.
