Potassium carbonate (8.0 mg, 58 μmol, 1.6 eq.) and tert-butyl bromoacetate (11.2 mg, 58 μmol, 1.6 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) in dry DMF (5 ml). The reaction mixture was stirred at RT for 12 h and then concentrated under reduced pressure, and the residue purified by preparative HPLC (Kromasil C18 column, 5 μm, 50×20 mm; mobile phase: acetonitrile-water-0.1% TFA). After lyophilization, the product was obtained as a solid (25 mg, 76% of theory).
