Morpholine → 4-{[5-Biphenyl-4-yl-4-(2-fluorophenyl)-4H-1,2,4-triazol-3-yl]methyl}morpholine

참여 물질

반응 단계

Morpholine (0.599 ml) was dissolved in N,N-dimethylformamide (6 ml), followed by addition of sodium hydride (60%, 275 mg) under ice cooling, and stirred at the same temperature for 30 minutes. Under ice cooling, 3-biphenyl-4-yl-5-chloromethyl-4-(2-fluorophenyl)-4H-1,2,4-triazole (599 mg) was added to the reaction solution, and stirred at ambient temperature for 17 hours. After the reaction solution was concentrated under reduced pressure, saturated aqueous sodium hydrogen carbonate solution was added to the resulting residue, followed by extraction with chloroform. The organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the resulting residue was purified by silica gel chromatography (eluent: toluene/acetone=3/2 to 1/1), and recrystallized from a mixture solution of n-hexane and ethyl acetate, to afford the entitled compound as white crystal (211 mg, 74%). The physico-chemical values are as follows.
