実験手順

(4S)-4-[4-Cyano-2-(methylsulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (1.00 g, 2.17 mmol; Example 6) and triethylamine (659 mg, 6.52 mmol) were, together with a spatula tip of 4-N,N-dimethylaminopyridine, suspended in dichloromethane (8.3 ml). 4-Nitrophenyl chloroformate (875 mg, 4.34 mmol) was then added. The resulting solution was stirred at room temperature for 5 min, and water (1 ml) was then added. Furthermore, toluene (7 ml) was added to the contents of the flask, and the mixture was concentrated under reduced pressure. The residue was subjected to flash chromatography on silica gel (mobile phase: dichloromethane). The concentrated product fractions were triturated with ethanol (20 ml), and the resulting solid was filtered off with suction. This gave the target compound (559 mg, 39% of theory).
