Reaction Steps

After dissolving 4-phenyl-2,4-dihydro[1,2,4]triazol-3-one (CAS 1008-30-6) (1.00 g) and 1,3-dibromopropane (1.89 ml) in N,N-dimethylformamide (15 ml), sodium hydride (60% in oil) (273 mg) was added and the mixture was stirred at room temperature for 4 hours. Water was added to the reaction mixture, and extraction was performed with ethyl acetate. The organic layer was washed with water and brine in that order and then dried over anhydrous magnesium sulfate. After filtration, the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography. The obtained solid was washed with n-heptane to obtain the title compound (840 mg).
