{1-[6-(3,4-Difluoro-phenoxy)-4-pyrimidin-2-yl-hexahydro-pyrrolo[3,2-b]pyrrole-1-carbonyl]-2,2-dimethyl-propyl}-carbamic acid benzyl ester → 2-Amino-1-[6-(3,4-difluoro-phenoxy)-4-pyrimidin-2-yl-hexahydro-pyrrolo[3,2-b]pyrrol-1-yl]-3,3-dimethyl-butan-1-one

Participants

Reaction Steps

A mixture of carbamate 29 (140 mg, 0.25 mmol) and 10% Pd-on-carbon (wet, 100 mg, 0.09 mmol) in MeOH (20 mL) was stirred vigorously under 1 atm H2. After 3 h, the catalyst was removed by filtration with an Acrodisc® 0.45 μm nylon membrane syringe filter and the solvent was removed in vacuo to afford 106 mg (100%) of 30 as a white solid which was used without further purification. Mass spectrum, m/z [431.8] (M+H)+.
