DBU-catalyzed esterification: A single esterification product was obtained from a molecule containing primary aniline, alcohol, phenol, secondary amide, and N−H indole groups. These acylation reactions are highly practical as they involve only readily available, inexpensive, and relatively safe reagents; can be performed on a multigram scale; and can be used on carboxylic acids directly by in situ formation

details, kinetic progress, and temperature-dependent product distribution, which revealed the slow and steady generation of in situ formed aldehyde, is the key factor to get the higher yield of the β-methylated product. To establish the environmental benefit of this reaction, green chemistry metrics are calculated. Furthermore, dimerization of 2-naphthol via methylene linkage and formation of N-methylation
The present invention refers to compounds of formula (I) or a pharmaceutically acceptable salt thereof: Formula (I). These compounds have FFA4/GPR120 receptor (FFA4) agonistic properties. The invention refers also to pharmaceutical compositions comprising these compounds, chemical processes for preparing them and their use in the treatment or prophylaxis of diseases associated with FFA4 receptor activity in animals, in particular humans.
Selective <i>N</i>-monomethylation of primary anilines with the controllable installation of <i>N</i>-CH<sub>2</sub>D, <i>N</i>-CHD<sub>2</sub>, and <i>N</i>-CD<sub>3</sub> units
The selective N-monomethylation of primary anilines with the controllable installation of N-CH2D, N-CHD2, and N-CD3 units was realized by using the amine-borane/N,N-dimethylformamide (DMF) system as the methyl precursor.
