2-Amino-5-nitropyridine CAS 4214-76-0

Loaʻa ka 2-Amino-5-nitropyridine CAS 4214-76-0 mai ka nitratation o 2-aminopyridine. Ma kahi mahana o 50 °C, ua hoʻohui ʻia ka 2-aminopyridine i ka sulfuric acid concentrated, a laila ua hoʻohui ʻia ka waika nitric fuming dropwise, a ʻaʻole i ʻoi aku ka mahana ma mua o 50 °C. Incubate ma 45 ° C no 2h, a hoʻoulu i ka lumi wela no 4h. Ua ninini ʻia ka hopena hopena i loko o ka hau hau, a ua hoʻoponopono ʻia ka pH i 6 ma ka hoʻohui ʻana i ka wai amonia ma lalo o 5 ° C, a ua hoʻoheheʻe ʻia nā kristal. E kānana a maloʻo. ʻO ka recrystallization me ka wai e loaʻa ai nā platelet melemele ʻeleʻele, e loaʻa iā 75%

E hoʻouna i ka nīnau
