Procedure

Under an atmosphere of argon protective gas and at room temperature, triethylamine (11.1 mg, 140 μmol, 2.6 eq.) and methanesulfonyl chloride (41 mg, 360 μmol, 10 eq.) were added to a solution of benzyl {(7R)-6-cyano-7-(4-cyanophenyl)-5-methyl-4-[3-(trifluoromethyl)phenyl]-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}carbamate (20 mg, 36 μmol; Example 38) in dry pyridine (2 ml) and THF (2 ml), and the mixture was stirred for 12 h. The reaction mixture was then concentrated under reduced pressure and directly purified by preparative HPLC (Reprosil C18 column, 30×200 mm; mobile phase: acetonitrile-water-0.1% TFA). After lyophilization, the product was obtained as a solid (17.4 mg, 72% of theory).
