Participants

Reaction Steps

Mixture of 4-[6-(2-fluoro-4-methanesulfonyl-phenylamino)-5-nitro-pyrimidin-4-yloxy]-piperidine-1-carboxylic acid isopropyl ester (197 mg, 0.3 mmole), Zn Dust (2.4 mmole, 8 eq) and 1 mL of Sat NH2Cl solution in 2 mL THF and 2 mL H2O was stirred at room temperature for 25 minutes. Zn Dust was filtered off by celite and washed with ethyl acetate. Crude was purified by column chromatography (Hexane/Ethyl Acetate=½, Rf=0.44) to give compound A120 as a yellow oil (100 mg, 71%). 1H NMR (DMSO-d6, 400 MHz) δ 1.19 (d, 6H), 1.62-1.68 (m, 2H), 1.88-1.93 (m, 2H), 3.23 (s, 3H), 3.33-3.39 (m, 2H), 3.64-3.70 (m, 2H), 4.77 (sep, 1H), 5.28-5.29 (m, 1H), 7.68 (d, 1H), 7.77 (d, 1H), 7.88 (s, 1H), 8.06 (t, 1H), 8.41 (sb, NH). Exact mass calculated for C20H26FN5O5S 467.2, found 468.5 (MH+).
