Reaction Steps

Under an atmosphere of argon protective gas, 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}(cyclopropyl-methyl)carbamate (20.0 mg, 33 μmol) was dissolved in degassed methanol (5 ml). After addition of palladium on activated carbon (10%; 5 mg), the mixture was hydrogenated under a hydrogen atmosphere (˜1 atm) at RT for 1.75 h. The reaction mixture was then filtered, the filtrate was 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 (10.9 mg, 70% of theory).
