Procedure

The reaction was carried out under argon. (4S)-4-[4-Cyano-2-(methylsulfanyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (240 mg, 0.536 mmol) was dissolved in THF (5 ml), and PyBOP (419 mg, 0.805 mmol) and triethylamine (380 mg, 3.76 mmol) were added. After brief stirring the mixture was cooled to 0° C., and ammonium chloride (143 mg, 2.68 mmol) was added. The reaction mixture was stirred at RT overnight and the content of the flask was then added to 1 N hydrochloric acid. The mixture was extracted twice with ethyl acetate, and the combined organic phases were washed with 1 N hydrochloric acid and with saturated sodium chloride solution, dried and concentrated. The residue was purified by preparative HPLC. This gave 161 mg (67% of theory) of the title compound.
