The article was titled 《A new approach to CF3-containing 3,4-dihydroquinazolin-2(1H)-ones》. The information in the text is summarized as follows:
A new approach to CF3-containing 3,4-dihydroquinazolin-2(1H)-ones based on the condensation of 5-acetyl-6-methyl-1-phenyl-4-trifluoromethylpyrimidin-2(1H)-one with DMF di-Me acetal was suggested. After reading the article, we found that the author used N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Related Products of 4637-24-5)
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.Related Products of 4637-24-5
