(2R,5R)-5-(Chloro-thiazol-2-yl-methyl)-4-{2-[6-(1,1-difluoro-butyl)-3,3-dimethyl-2,3-dihydro-pyrrolo[3,2-c]pyridin-1-yl]-2-oxo-ethyl}-2-methyl-piperazine-1-carboxylic acid tert-butyl ester (0.03 g, 0.05 mmol), Pd/C (0.01 g, 0 mmol), triethylamine (0.01 g, 0.1 mmol) were dissolved in EtOAc (0.2 mL) and hydrogenated at room temperature and 1 bar for 30 minutes, followed by hydrogenation at 40 psi in a Parr hydrogenator for 1 h. The reaction was filtered and solids washed with EtOAc. The filtrate was concentrated and the crude product was purified by column chromatography (silica gel, gradient elution, 0-100%, EtOAc in petrol 40-60), to give the title compound (0.011 g). MS: [M+H]+=578.
