Reaction Steps
The compound of step 1 (140 mg, 0.424 mmol) was dissolved in ethanol (10 ml) and 12 N hydrochloric acid (0.2 ml), palladium on charcoal (10%) was added, and the mixture was hydrogenated at a hydrogen pressure of 6 bar at room temperature overnight. After filtration and evaporation, the residue was purified by silica gel chromatography (HEP/EA gradient) to give 80 mg of the title compound.
