Versuchsvorschrift

A 20-mL vial was charged with ethyl 2-(4-((2-(3-chlorophenyl)-6-cyclopropylpyridin-4-yl)amino)phenyl)acetate (0.090 g, 0.23 mmol), dioxane (1 mL) and methanol (3 mL). To this solution was added NH3 (6.0 mL, 7N in methanol, 42.0 mmol). The vial was sealed and the resulting mixture was stirred at 100° C. for 47 h. The crude reaction mixture was concentrated under reduced pressure. The residue was adsorbed onto silica then purified by chromatography on silica using hexanes/ethyl acetate (10:0 to 0:10) as eluent followed by chromatography on silica using dichloromethane/methanol (10:0 to 9:1) as eluent to afford 2-(4-((2-(3-chlorophenyl)-6-cyclopropylpyridin-4-yl)amino)phenyl)acetamide (0.024 g, 27%) as a colorless oil. MW=377.87. 1H NMR (CDCl3, 500 MHz) δ 7.94-7.91 (m, 1H), 7.81-7.76 (m, 1H), 7.36-7.31 (m, 2H), 7.30-7.26 (m, 2H), 7.21-7.17 (m, 2H), 7.01 (d, J=2.0 Hz, 1H), 6.68 (d, J=2.5 Hz, 1H), 6.02 (s, 1H), 5.45 (br s, 2H), 3.58 (s, 2H), 1.99-1.93 (m, 1H), 1.13-1.08 (m, 2H), 0.97-0.92 (m, 2H); ESI MS m/z 378 [M+H]+. Treatment with 1.25M HCl (0.103 mL, 0.130 mol) in methanol afforded the title compound (0.022 g, 84%) as an off-white solid. MW=414.33. M.p. 104-106° C. 1H NMR (DMSO-d6, 500 MHz) δ 13.48 (br s, 1H), 8.78 (br s, 1H), 7.92 (d, J=1.0 Hz, 1H), 7.84-7.76 (m, 1H), 7.52 (br s, 2H), 7.45 (s, 1H), 7.30-7.25 (m, 2H), 7.25-7.16 (m, 2H), 7.11 (s, 1H), 6.87 (s, 1H), 6.74 (s, 1H), 3.36 (s, 2H), 2.15-2.02 (m, 1H), 1.10-0.90 (m, 4H); ESI MS m/z 378 [M+H]+.
