Reaction Steps

A mixture of (R)-methyl 3-((2-chloro-5-nitropyrimidin-4-yl)(3,3-difluorocyclopentyl)amino)-2,2-dimethylpropanoate (2.74 g, 6.98 mmol) and iron powder (0.799 g, 14.31 mmol) in glacial acetic acid (30 mL) was heated to 70° C. for 2 hours. The reaction mixture was filtered hot and the cake was further washed with acetic acid. The mother liquors were concentrated in vacuo. The residue was taken up in a 15% solution of methanol in dichloromethane and filtered through a pad of silica gel rinsing with more methanol-dichloromethane solution. The filtrates were concentrated in vacuo. The residue was triturated with methanol and the solid was filtered to afford the title compound as an off-white solid (1.67 g, 72% yield).
