The reaction was stirred at RT for 30 min. However when the ammonium carboxylate salt is heated to a temperature above 100 o C water is driven off and an amide is formed. Sometimes the name for this reaction is also used to indicate the reaction between an acid chloride and an alcohol to form an ester. To a solution of the acid (700 mg, 3.2 mmol) in DMF (10 mL) was added DIEA (1.25 g, 9.7 mmol). An amide name is based on the name of the carboxylic acid of the same number of carbon atoms, but the ‐oic ending is changed to amide. After the amidation reaction, the reaction mixture contains the amide product, borate-ester derived byproducts, and potentially some unreacted amine and/or carboxylic acid.

It also serves as an alternative way to navigate the website, and as a means of coming up with retrosynthetic ideas. Benzylamine reacts with acetyl chloride under Schotten-Baumann conditions to form N-benzylacetamide.

The mixture was cooled to 0 C and treated with EDC-HCl (1.2 g, 6.5 mmol), HOBt (879 mg, 6.5 mmol), and the amine (473 mg, 4.9 mmol). In our preliminary report, the amidation reactions were purified by acid and base washes to remove these impurities. Boron mediated amidation reactions have attracted consid-erable attention,9−12 and boronic acids have been shown to be effective catalysts for direct amide formation from carboxylic acids and amines.9 In general, boronic acid catalyzed amidation reactions require the removal of water from the reaction either General Reaction. Amides with alkyl groups on the nitrogen are substituted amides and are named the same as N‐substituted amides, except the parent name is preceded by the name of the alkyl substituent and a capital N precedes the substituent name. Conversion of Carboxylic Acids to Amides.

Amides Preparation and Reactions Summary.

The Schotten–Baumann reaction is a method to synthesize amides from amines and acid chlorides: An example of a Schotten-Baumann reaction. The reaction map is intended to provide insight into possible reactions one step before and after the title reaction. Click on the reaction arrow to visit the page. The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate. Amides can be prepared from acyl chlorides, esters and carboxylic acids.
