Reaction Steps

366 mg (1.25 mmol) (R)-1-(2-amino-6-nitro-benzoyl)-2-methyl-pyrrolidine-2-carboxylic acid are dissolved in 50 mL methanol and combined with 40 mg palladium on charcoal (10% Pd). The reaction mixture is hydrogenated for 9 h at 5 bar hydrogen pressure and at 25° C. Then the catalyst is filtered off, the solvent is eliminated in vacuo and the crude product is purified by chromatography. The carrier material used is C18-RP-silica gel and a gradient is run through which consists of 95% water and 5% acetonitrile at the starting point and 5% water and 95% acetonitrile at the end point.
