Sakamoto, Takao; Satoh, Chisato; Kondo, Yoshinori; Yamanaka, Hiroshi published an article on January 31 ,1993. The article was titled 《Condensed heteroaromatic ring systems. XXI. Synthesis of pyrrolo[2,3-d]pyrimidines and pyrrolo[3,2-d]pyrimidines》, and you may find the article in Chemical & Pharmaceutical Bulletin.Category: pyrimidines The information in the text is summarized as follows:
The title compounds, e.g., I and II were synthesized in high yields by the palladium-catalyzed reaction of 4-acetylamino-5-bromopyrimidines and 5-acetylamino-4-iodopyrimidines with (Z)-1-ethoxy-2-(tributylstannyl)ethene followed by cyclization under acidic conditions.4-Chloro-6-methoxy-5-nitropyrimidine(cas: 52854-14-5Category: pyrimidines) was used in this study.
4-Chloro-6-methoxy-5-nitropyrimidine(cas: 52854-14-5) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Category: pyrimidines
