Reaction Steps

To a solution of 50 mg of 1-(4-{4-[3-(4-Amino-phenylamino)-[1,2,4]triazol-1-yl]-pyridin-2-yl}-2,6-dimethyl-piperazin-1-yl)-ethanone (0.123 mMol. 1.00 equiv) in 2 mL of NMP was added 5 mL of CH2Cl2 and 500 μL of Hunig's base followed by 100 μL of 2-furanoyl chloride (1.01 mMol, 8.13 equiv). The reaction mixture was stirred for 1 hr and concentrated. The resulting oil was purified via flash chromatography (EtOAc) to yield 1.4 mg of Furan-2-carboxylic acid (4-{1-[2-(4-acetyl-3,5-dimethyl-piperazin-1-yl)-pyridin-4-yl]-1H-[1,2,4]triazol-3-ylamino}-phenyl)-amide (0.0028 mMol, 2.3% yield). 1H NMR (500 MHz, MeOD-d4) ∂ 8.95 (1H, s), 8.18 (1H, d), 7.72 (1H, m), 7.61 (4H, m), 7.25 (2H, m), 7.15 (1H, m), 6.61 (1H, s), 4.30 (2H, m), 3.30 (2H, m), 3.15 (2H, m), 2.20 (3H, s), 1.35 (6H, m) ppm. LC/MS: 2.2 min/501.3 (M+1).
