Reaction Conditions

Reaction Steps

Under an atmosphere of argon protective gas and at 0° C., HATU (25 mg, 66 μmol, 3 eq.) and triethylamine (11 mg, 110 μmol, 5 eq.) were added to a solution of N-{(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}glycine (10.5 mg, 22 μmol) in DMF (1 ml). After the reaction mixture has thawed to RT, it was once more cooled to 0° C., and a 0.5 M solution of ammonia in dioxane (0.44 ml, 219 μmol, 10 eq.) was then added. The mixture was stirred for 2 h, during which time it gradually warmed to RT. The reaction mixture was then concentrated under reduced pressure and the residue was purified by preparative HPLC (Kromasil C18 column, 50×20 mm; mobile phase: acetonitrile-water-0.1% TFA). After lyophilization, the product was obtained as a solid (9.2 mg, 88% of theory).
