Versuchsvorschrift

In a 1-L round bottom flask, 10.00 g (0.0528 mol) of 2,6-difluoro-3,5-dimethoxy-phenylamine and 12.42 g (0.0523 mol) of 4-cyclopentylamino-2-methylsulfanyl-pyrimidine-5-carbaldehyde in 500 mL of toluene with 3.65 g (0.0157 mol) of camphorsulfonic acid was fitted with a Dean Stark trap and heated at reflux. During the day, the toluene was drained three times from the finger and continued heating at reflux under nitrogen atmosphere overnight. The toluene was concentrated in vacuo and dried to give 25.30 g (quantitative) of the title compound. No further purification was necessary. MS (APCI) (m+1)/z 409.2.
