Reaction Steps

4.05 g (15.27 mmol) of the product prepared in step 18.1 in 25 mL of an ethyl acetate/ethanol mixture (v/v=1/1) are placed in a hydrogenation autoclave, and 0.32 g of 10% palladium-on-charcoal is added, under an inert atmosphere. The mixture is stirred under a hydrogen pressure of 2.5 bar at room temperature for 2 hours. After filtering through thin glass fibre paper and evaporating under reduced pressure, 3.51 g of the expected product are obtained in the form of a violet solid, which is used as obtained in the following step. Yield=98%.
