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 (4 ml), a 7 N solution of ammonia in methanol (5 ml) was added and the mixture was stirred at RT for 60 min. The reaction mixture was then concentrated under reduced pressure, and the residue was triturated with acetonitrile (3 ml). The crystals formed were filtered off with suction, washed with acetonitrile and water and, for further purification, separated by preparative HPLC [column: Sunfire C-18, 5 μm, 19 mm×150 mm; sample preparation: the sample was dissolved in 3 ml of acetonitrile+3 ml of 1% strength aqueous TFA solution+2 ml of THF; injection volume: 1000 μl; mobile phase: acetonitrile/water/1% aq. TFA 25:60:15 (0-12 min); flow rate: 25 ml/min; temperature: 40° C.; detection: 210 nm]. This gave 59 mg (36% of theory) of the target compound.
