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), 2-aminoethanol (62.5 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 98 mg (54% of theory) of the title compound.
