N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Product Details of 116332-61-7

And the article was included in Bulletin of the Korean Chemical Society in 2006.Product Details of 116332-61-7 This article mentions the following:

CF3CCH reacted with Weinreb amides in BuLi/THF to give CF3CCl:CHCOR [R = (un)substituted Ph, 1-naphthalenyl, 2-furanyl, cyclohexyl] as E-Z mixtures In the experiment, the researchers used many compounds, for example, N-Methoxy-N-methyl-4-(trifluoromethyl)benzamide (cas: 116332-61-7Product Details of 116332-61-7).
