実験手順
To a solution of 4,6-dichloro-2-(methylthio)-5-pyrimidinecarbaldehyde (10.0 g, 44.8 mmol) in THF (250 mL) was added 2,6-difluoroaniline (5.35 mL, 49.3 mmol, 1.1 eq) followed by Et3N (12.6 mL, 89.6 mmol, 2 eq). The reaction mixture was heated to 55° C. for about 22 h before concentrated. The slurry was re-dissolved in DCM (250 mL) and washed with H2O (2×100 mL), then concentrated and further washed with acetone (2×10 mL) to give 9.87 g (70%) of pure 4-chloro-6-[(2,6-difluorophenyl)amino]-2-(methylthio)-5-pyrimidinecarbaldehyde. LC-MS m/z 316 (M+H)+.
