4-氯-5-羟基3(2H)-哒嗪性质、用途与生产工艺
4-氯-5-羟基3(2H)-哒嗪是一种有机中间体。
Wagner等人报道了其可由4,5-二氯哒嗪-3(2H)-酮作为起始物料制备得到。将4,5-二氯哒嗪-3(2H)-酮（2g，12mmol）在20ml 8N KOH中回流6小时。用HCl酸化后，将反应混合物真空浓缩，并用乙酸乙酯萃取得到4-氯-5-羟基3(2H)-哒嗪。产率0.69g，54％。m.p.267-272°C(from DMF),Lit.270-273°C.IR:2300-3340re,b,1650m,1595s,1555shcm-1.1H-NMR(DMSO-d6):δ=7.7(s,HatC-6),12.9(s,b,NH).C4H3C1N2O2(146.5);calcd.C32.78,H2.06,N19.12;foundC32.75,H2.17,N19.06。
