Procedure

Under an atmosphere of argon protective gas, (7R)-2-amino-7-(4-cyanophenyl)-5-methyl-4-[3-(trifluoromethyl)phenyl]-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidine-6-carbonitrile hydrochloride (14 mg, 31 μmol) was dissolved in abs. pyridine (0.7 ml). At room temperature, 2-[2-(2-methoxyethoxy)ethoxy]acetyl chloride (12 mg, 61 μmol, 2 eq.) was added. After 12 h, analysis of the reaction by HPLC showed substantial conversion. The reaction mixture was concentrated under reduced pressure and purified by preparative HPLC (Gromsil C18 column, 30×250 mm; mobile phase: acetonitrile-water-0.1% TFA). After lyophilization, the product was obtained as a solid (12.4 mg, 70% of theory).
