Procedure

In a 500-mL round bottom flask, 3.00 g (15.86 mmol) of 2,6-difluoro-3,5-dimethoxy-phenylamine and 3.13 g (15.86 mmol) of 4-ethylamino-2-methylsulfanyl-pyrimidine-5-carbaldehyde in 150 mL of toluene with 1.11 g (4.76 mmol) of camphorsulfonic acid was fitted with a Dean Stark trap and heated at reflux. During the day, the toluene was drained 3 times from the finger, replenished with 100 mL of the solvent and continued heating at reflux under nitrogen atmosphere overnight. The toluene was concentrated in vacuo and dried to give 7.19 g (quantitative) of the title compound. No further purification was necessary. MS (APCI) (m+1)/z 369.1.
