(4-tert-Butoxycarbonylamino-2-nitro-phenylamino)-acetic acid tert-butyl ester → Glycine,n-[2-amino-4-[[(1,1-dimethylethoxy)carbonyl]amino]phenyl]-,1,1-dimethylethyl ester

Participants

Reaction Steps

(4-tert-Butoxycarbonylamino-2-nitro-phenylamino)-acetic acid tert-butyl ester (10.8 g, 29.4 mmol) was dissolved in MeOH (70 mL) and purged with N2. Palladium on activated carbon (2.2 g, 10% by weight) was added, and the reaction mixture was charged with a balloon of H2. The reaction mixture was stirred for 3 h at room temperature, and then filtered through a pad of celite. The celite was washed with MeOH, and the filtrate was concentrated to afford 2.1 g (22%—two steps) of the sub-title compound. MS calculated for C17H27N3O4+H: 338, observed: 338.
