Reaction Steps

To a suspension of (S)—N2-(5-cyclopropyl-1H-pyrazol-3-yl)-N6-[1-(4-fluorophenyl)ethyl]-3-nitropyridine-2,6-diamine (Example 47; 0.26 g, 0.68 mmol) and zinc dust (0.223 g, 3.41 mmol) in MeOH:THF (1:1, 12 ml) was slowly added saturated ammonium chloride solution (1.5 ml). The reaction mixture was stirred at 25° C. for 1 hour, to which was then added saturated ammonium acetate solution (5 ml). The resulting mixture was stirred for another 30 minutes. Zn dust was removed by filtration and washed with EtOAc (20 ml). The organic layer was separated, washed with brine (10 ml), dried over Na2SO4, and concentrated to give the title compound.
