Procedure

0.41 g of palladium-on-charcoal and 4.1 g (64.32 mmol) of ammonium formate are added to a solution of 3.2 g (12.86 mmol) of the product prepared in step 24.2 in 120 mL of methanol, under argon, and the mixture is refluxed for 2 hours. After filtration, the filtrate is concentrated to dryness to give 2.6 g of the expected product in the form of a light-brown solid, which is used as obtained in the following step. Yield=92%.
