Reaction Steps

To a solution of 3-(4-fluorophenyl)-1H-1,2,4-triazol-5-amine (100 mg, 0.56 mmol) in n-BuOH (3 ml) was added TsOH (5 mg, 0.03 mmol), and ethyl 3-(4-chloro-3-methoxyphenyl)-3-oxopropanoate (200 mg, 0.78 mmol), and the resulting mixture was stirred for 36 hours at 130° C. in an oil bath. The solids were collected by filtration to give a crude product, which was purified by Flash-Prep-HPLC to afford 5-(4-chloro-3-methoxyphenyl)-2-(4-fluorophenyl)-[1,2,4]triazolo[1,5-α]pyrimidin-7(4H)-one as a white solid (33.5 mg, 16%).
