Reaction Steps
In a microwave tube, 4-[6-[(2R)-2-ethyl-1-pyrrolidinyl]-2-(methylamino)-4-pyrimidinyl]-2-fluoro-6-(methyloxy)benzonitrile (129 mg, 0.363 mmol), 5 mL of EtOH, Hunig's base (0.063 mL, 0.363 mmol), and hydrazine anhydrous (0.068 mL, 2.178 mmol) were added. The yellow suspension mixture was heated to 100° C. in an oil bath overnight. When the temperature of the reaction reached 100° C., the solid in the mixture was all dissolved. After overnight, there was a white colored solid formed. LCMS showed no more starting material. The reaction was cooled to room temperature, then the white solid was filtered from the yellow solution, washed by CH3CN (2 mL), and dried under reduced pressure to afford the title compound (70 mg) as a white solid. LC-MS (ES) m/z=368 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 0.90 (t, J=7.3 Hz, 3H), 1.37 (m, 1H), 1.80 (m, 2H), 1.93 (m, 3H), 2.82 (d, J=4.6 Hz, 3H), 3.39 (m, H), 3.47-3.63 (m, 1H), 3.93 (s, 3H), 4.05 (m, 1H), 5.02 (s, 2H), 6.19 (s, 1H), 6.41 (s, 1H), 6.92 (s, 1H), 7.46 (s, 1H), 11.51 (s, 1H).
