Ib tug benzylamine derivative ua ib tug potassium channel thaiv tus neeg sawv cev. N- (4-fluorophenyl) phthalimide 25.5g (0.1mol) thiab 25ml anhydrous ethanol tau ntxiv rau hauv 100ml cov tshuaj tiv thaiv lub khob, ua raws li 6.3g (0.1mol) ntawm 80% hydrazine hydrate tov, thiab rhuab reflux 0.5g. Ntxiv cov hydrochloric acid ntau dhau kom decompose cov precipitated dawb precipitate. Tom qab txias, ntxiv ib qho dej kom tsim nyog rau do thiab lim. Cov filtrate tau neutralized nrog NaOH tov thiab muab rho tawm nrog ethyl ether. Cov ethyl ether extract tau qhuav thiab tom qab ntawd steamed kom tshem tawm cov ethyl ether. Cov feem ntawm 44-46 ℃ (67kPa) tau sau los ntawm lub tshuab nqus tsev distillation kom tau 7.1g p-fluorobenzylamine nyob rau hauv yield ntawm 56.5%.
