Use | the anti-allergic drug astemizole, an intermediate of the analgesic drug Flupirine. used as pharmaceutical and pesticide intermediates |
production method | add N-(4-fluorobenzyl) phthalimide 25.5g(0.1mol) to a ML reaction flask 80% g (6.3 mol) of 0.1 hydrazine hydrate solution was added thereto, followed by heating to reflux for 0.5g. An excess of hydrochloric acid is added to decompose the precipitated white precipitate. After cooling, an appropriate amount of water is added and stirred, and suction filtration is carried out. The filtrate was neutralized with NaOH solution, extracted with diethyl ether, the diethyl ether extract was dried, and then the diethyl ether was distilled off under reduced pressure to collect a 44-46 ° C. (67kPa) fraction to give 7.1g of p-fluorobenzylamine in a yield of 56.5%. |
