A preparative method for producing of 3-(4′-methylphenyl)-8-methylxanthine, its 7-substituted derivatives, 3-(4′-methylphenyl)-8-methylxanthinyl-7-acetic acid, its ester, amide, hydrazide, ylidenehydrazides, and N-phenylhydrazinocarbothiamide was developed. The structure of the cyclization product of the last, 3-(4′-methylphenyl)-7-[2-(4″-phenyl-5″-thio-4″H-[1″,2″,4″]triazol-3″-yl)methyl]xanthine, was confirmed by elemental analysis and PMR spectroscopy.
开发了一种制备3-(4′-甲基苯基)-8-甲基黄嘌呤、其7-取代衍生物、3-(4′-甲基苯基)-8-甲基黄嘌呤-7-乙酸、其酯、酰胺、酰肼、亚肼基化合物以及N-苯基酰肼硫脲的方法。最后一种化合物的环化产物结构,即3-(4′-甲基苯基)-7-[2-(4″-苯基-5″-硫-4″H-[1″,2″,4″]三唑-3″-基)甲基]黄嘌呤,通过元素分析和PMR光谱得以确认。
