The reaction mixture was stirred under H2 (g) atmosphere (balloon) for 21 h. It was filtered through Celite washing with AcOEt (2×10 mL), the solvent was concentrated off and the crude was purified by flash chromatography on silica gel (CH2Cl2/MeOH/NH4OH 95:5:1), to yield 0.178 g of the title product (Rf=0.2 (AcOEt/MeOH/Et3N 20:3:2), pale yellow colored oil, 84% yield).
