实验过程

Ammonium formate (1.01 g, 16.0 mmol) and 10% Pd/C 42.5 mg, 0.4 mmol, 10 mol%) were added successively to a stirred solution of the product of Example 21 (1.23 g, 4.06 mmol) in methanol (4 ml). The mixture was stirred at room temperature for 6 h and was heated at 75° C. for 16 h. Methanol (40 ml) was added and the mixture filtered through Kieselguhr, and concentrated in vacuo to give the product as a pale yellow oil.
