Aromatic carboxylic acid trifluoro ethyl ester compound and its preparation method. The present invention provides a kind of aromatic carboxylic acid trifluoroacetate ester compound and its preparation method, the method is that the aromatic carboxylic acid and nitrous acid tert-butyl and 2, 2, 2 - trifluoro ethylamine one-pot synthesis after reaction, to obtain the carboxylic acid trifluoroacetate ester compound. The method is simple in operation, mild reaction conditions, low cost, few by-products, high yield, can be aromatic carboxylic acid trifluoroacetate ester compound, not limited by substrate, in order to establish aromatic carboxylic acid trifluoroacetate ester compound library, for drug screening and new drug synthesis of the raw material sources.

We describe an efficient approach for the synthesis of N-substituted 2-alkenylamides in trifluoroethanol via an Ugi 4-component reaction in short reaction times. The use of a catalytic amount of sulfuric acid in trifluoroethanol gave the desired trifluoroethyl derivatives in good to high yields.
