Versuchsvorschrift

Into a sealable tube, 2-fluoro-4-{2-(methylamino)-6-[(2R)-2-methyl-1-pyrrolidinyl]-4-pyrimidinyl}-6-(methylthio)benzonitrile (86 mg, 0.241 mmol), EtOH (5 mL), Hunig's base (0.042 mL, 1.44 mmol), and hydrazine anhydrous (0.045 mL, 0.241 mmol) were added, and the yellow suspension mixture was heated overnight at 100° C. in an oil bath. After overnight, there was yellow solution as well as a little amount of white colored solid formed. LCMS showed no more starting material. The reaction was cooled to room temperature. Water (20 mL) was added to the yellow solution, and a solid was formed. The solid was filtered, washed by water, and dried in vacuum. The solid was further purified by flash column chromatography. The fractions containing product were combined, and the solvent was removed under reduced pressure to afford the title compound (20.5 mg) as a white solid. LC-MS (ES) m/z=370 [M+H]+. 1H NMR (400 MHz, DMSO-d6): δ 1.21 (d, J=6.1 Hz, 3H), 1.67 (m, 1H), 1.84-2.10 (m, 3H), 2.61 (s, 3H), 2.79-2.91 (m, 3H), 3.41-3.66 (m, 2H), 4.27 (m, 1H), 5.09 (s, 2H), 6.23 (s, 1H), 6.44 (s, 1H), 7.34-7.46 (m, 1H), 7.72 (s, 1H), 11.75 (s, 1H).
