Versuchsvorschrift

2-Cyanoethyl 4-(4-cyanophenyl)-6-methyl-2-thioxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydro-5-pyrimidinecarboxylate (Example 16; 47 mg, 0.1 mmol) is dissolved in 0.5 ml dioxane. After addition of 1,8-diazabicyclo[5.4.0]undec-7-ene (15 μl, 15 mg, 0.1 mmol), the reaction mixture is stirred at room temperature for 3 hours. The reaction mixture is diluted with 1 N hydrochloric acid and extracted with ethyl acetate. After drying with magnesium sulfate and evaporating off the solvent, the residue is purified by preparative HPLC (column: Nucleosil 100-5 C 18 Nautilus 20 mm×50 mm, 5 μm; solvent A: acetonitrile, solvent B: water+0.1% formic acid; flow rate: 25 ml/min; gradient: 0 min 10% A, 2 min 10% A, 6 min 90% A, 7 min 90% A, 7.1 min 10% A, 8 min 10% A; wavelength: 220 nm; injection volume: approx. 550 μl; number of injections: 1). The product containing fractions are combined and concentrated in vacuo.
