2-Amino-5-fluorobenzoic acid CAS 446-08-2 Tono

Ko te waikawa 5-Fluoroanthranilic i whakahiato mai i te 2-methyl-4-fluoronitrobenzene hei rauemi timatanga. Ka whakamahia e ia a Raney nickel hei whakakorikori me te whakaheke i te hauwaitanga catalytic ki te 2-methyl-4-fluoronitrobenzene i te 50 °C. I muri i te tātari i te whakakorikori i roto i te Chemicalbook, ka tangohia te whakarewa ma te whakakore kia whiwhi 5-fluoro-2-aminotoluene. , a ka oxidized ki te pāhare pāporo, waikawa me te tātari ki te whiwhi i te hua masivesivá, ka purea e te rerenga waikawa alkali-wairewa ki te whiwhi i te hua ūnga whakamutunga parakore.
