Reaction Steps

To a suspension of (S)-N4-(5-cyclopropyl-1H-pyrazol-3-yl)-N2-[1-(4-fluorophenyl)ethyl]-5-nitropyrimidine-2,4-diamine (Method 9; 0.8 g, 2.0 mmol) and zinc dust (0.7 g, 10.0 mmol) in MeOH:THF (1:1, 50 ml) was slowly added saturated NH4Cl solution (10 ml) at 25° C. After 3 hours, the reaction mixture was treated with saturated aqueous NH4OAc solution (40 ml) and allowed to stir for 30 minutes. The reaction was then filtered through a plug of celite with EtOAc (100 ml), and the resulting aqueous layer was extracted with EtOAc (2×100 ml), dried, filtered, and concentrated to give the title compound (0.04 g, 5%). MS: Calcd.: 353; Found: [M+H]+ 354.
