Vorschrift

To a solution of 15 (1.0 g, 3.7 mmol) in MeOH (30 mL) were added aqueous HCl (conc., 0.32 mL) and palladium, 10 wt. % (dry basis) on activated carbon (wet, Degussa type E101 NE/W, 307 mg, Aldrich). It was hydrogenated at 22 psi for 0.5 h. The mixture was filtered through a Celite cake and the solvent evaporated to dryness. Product 16 was obtained as an off white solid (1.0 g; yield 91.0%).
