Participants

Reaction Steps

Potassium carbonate (15.7 mg, 113 μmol, 2.1 eq.), 18-crown-6 (30 mg, 113 μmol, 2.1 eq.) and 1-iodo-2-methylpropane (21 mg, 113 μmol, 2.1 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 (30 mg, 54 μmol) in DMF (2 ml). The reaction mixture was stirred at RT for 12 h and then concentrated under reduced pressure. The residue was acidified with acetic acid (3 eq.) and then 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).
