At room temperature, a 0.5 M solution of ammonia in dioxane (25.79 ml, 12.9 mmol; 10 eq.) and triethylamine (130 mg, 1.3 mmol; 1 eq.) were added to 5-cyano-2-{(4S)-5-cyano-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidin-4-yl}benzenesulfonyl chloride (3.10 g, content 20%, 1.29 mmol), and the mixture was stirred overnight. The reaction mixture was then concentrated under reduced pressure, water/acetonitrile (˜10:1) was added to the residue and the solution was lyophilized. The substance obtained was dissolved in acetonitrile and then purified by preparative HPLC (column: Waters Sunfire C18, 5 μm; column dimensions: 250 mm×20 mm; detection: 240 nm; temperature: 28° C.; flow rate: 25 ml/min; injection volume: 500 μl; mobile phase: acetonitrile/0.2% trifluoroacetic acid 45:55). The title compound was obtained as a solid (0.155 g, 26% of theory).
