Procedure

(rac)-Ethyl 6-(bromomethyl)-4-[4-cyano-2-(methylsulfonyl)phenyl]-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylate (200 mg, 0.34 mmol; Example 13A) was dissolved in acetonitrile (5 ml), ethylamine (46.1 mg, 1.02 mmol) was added and the mixture was stirred at RT overnight. The reaction mixture was then purified directly by preparative HPLC (column: Kromasil C18, 125 mm×20 mm, 5 μm, 100 Å; mobile phase A: water with 0.01% formic acid, mobile phase B: acetonitrile; gradient: 0 min 10% B→2 min 10% B→9 min 90% B→12 min 90% B→12.1 min 10% B→15 min 10% B; flow rate: 0.35 ml/min; UV detection: 254 nm). This gave 120 mg (70% of theory) of the title compound.
