    • 4, the organic layer was evaporated to yield an oily residue, which was diluted with diisopropyl ether and set to crystallize. Crystalline 5 was filtered (26 g, 0.095 mol, 48% yield). Compound 5 (23 g, 0.084 mol) was dissolved in MeOH (250 mL), 10% Pd-C (3 g) was added and the mixture was hydrogenated during 16 h. The catalyst was filtered, and the filtrate was evaporated to give 1 (13.5 g, 95%).
