Reaktionsschritte

A solution of intermediate x75 (600 mg, 2.04 mmol), ammonium formiate (644 mg, 5 eq, 10.21 mmol) and palladium on charcoal (10% wt, 109 mg, 0.1 mmol) in a 1 to 1 mixture of THF and methanol (20 ml) is allowed to react at ambiant temperature for 16 hours. After filtration on celite and solvent evaporation, the crude product is purified using preparative chromatography on silicagel to furnish a crude compound which is recristallized in a mixture of CH2Cl2 and hexane to furnish 1-[(6-amino-9H-purin-9-yl)methyl]-4-propylpyrrolidin-2-one 283 as a white crystalline product (320 mg).
