Reaction Steps

4-Methyl-5-(2-methyl-5-quinolinyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (400 mg) was reacted with 1-bromo-4-chloro-butane (0.233 ml) and NaH (60%, 69 mg) in absolute EtOH (6.5 ml) at reflux for 45 min. Ethyl acetate was added, the insoluble salts were filtered off and the solvent was evaporated under reduced pressure. The crude was purified on silica gel (eluent: ethyl acetate to ethyl acetate/acetone, 1/1) affording the desired compound as pale yellow solid (430 mg, 79% yield).
