Procedure
A 10-mL vial was charged with ethyl 2-(6-((2-(3-chlorophenyl)-6-cyclopropylpyrimidin-4-yl)amino)pyridin-3-yl)acetate (0.070 g, 0.17 mmol) and NH3 (4.9 mL, 7N in methanol, 34.2 mmol). The vial was sealed and the resulting mixture was stirred at 100° C. for 23 h. The crude reaction solution concentrated under reduced pressure. The residue was absorbed on silica (2 g) then purified by chromatography on silica using dichloromethane/methanol (10:0 to 9:1) as eluent to afford the title compound (0.029 g, 45%) as a white solid. M.p. 232-235° C. 1H NMR (DMSO-d6, 500 MHz) δ 10.10 (s, 1H), 8.31-8.29 (m, 1H), 8.27 (dt, J=7.5, 2.0 Hz, 1H), 8.19 (d, J=2.0 Hz, 1H), 7.75-7.69 (m, 1H), 7.67 (dd, J=8.5, 2.0 Hz, 1H), 7.60 (br s, 1H), 7.58-7.52 (m, 2H), 7.50 (br s, 1H), 6.93 (br s, 1H), 3.37 (s, 2H), 2.07 (septet, J=4.5 Hz, 1H), 1.14-1.09 (m, 2H); 1.06-1.00 (m, 2H); APCI MS m/z 380 [M+H]+.
