Reaction Steps

To a solution of 3-amino-6-chloro-5-(1,1-difluoro-ethyl)-pyrazine-2-carboxylic acid [6-((R)-2-amino-5,5-difluoro-4-methyl-5,6-dihydro-4H-[1,3]oxazin-4-yl)-5-fluoro-pyridin-2-yl]-amide [Example 34] (54 mg, 0.113 mmol) in MeOH/THF (1:1, 10 ml) was added Pd/C 10% (BASF 4505 D/R E, 12 mg) and the mixture was set under an hydrogen atmosphere. After 2.5 h more Pd/C 10% (BASF 4505 D/R E, 11 mg) was added and the hydrogenation continued for another 2.5 h. The reaction mixture was filtered through a pad of Celite, washed with MeOH and the solvent evaporated. The residue was purified by chromatography on silica gel (DCM to DCM/MeOH 9:1) to provide the title compound as yellow foam.
