Reaction Steps

1,1-dimethylethyl-3-{[(3-{5-amino-6[(methylamino)carbonyl )pyrazin-2-yl}phenyl}carbonyl}amino}pyrrolidine-1-carboxylate (0.7 g, mmol) was suspended in dichloromethane (4 mL) and TFA (3 mL) was added. The mixture was stirred at ambient temperature for 2 hr. After removal of volatiles under reduced pressure, the residue was partitioned between saturated solution K2CO3 (300 mg) and dichloromethane (10 mL). The organic layer was separated, dried (Na2SO4) and evaporated to dryness to afford 0.4 g (74% yield) of 3-amino-N-methyl-6-(3-{[(3R)-pyrrolidin-3-ylamino]carbonyl}phenyl) pyrazine-2-carboxamide. 1H NMR (400 MHz; DMSO-D6): 8.9 (s, 1H); 8.85 (m, 1H); 8.71 (d, 1H); 8.48 (m, 1H); 7.4 (d, 1H); 7.84 (d, 1H); 7.6 (t, 1H); 4.54 (m, 2H); 3.6-3.18 (m, 4H); 2.85 (d, 3H); 2.25 (m, 1H); 2.1 (m, 1H); MS (EI) for C17H20N6O2: 341 (MH+)
