3-Amino-4-methoxybenzonitrile (cas: 60979-25-1) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. In conventional organic reductions, nitrile is reduced by treatment with lithium aluminium hydride to the amine. Reduction to the imine followed by hydrolysis to the aldehyde takes place in the Stephen aldehyde synthesis, which uses stannous chloride in acid.Reference of 60979-25-1

Silica-sulfuric acid: novel, simple, efficient and reusable catalyst for hydration of nitrile to amide was written by Chandrashekharappa, Sandeep;Venugopala, Katharigatta N.;Venugopala, Rashmi;Odhav, Bharti. And the article was included in Asian Journal of Chemistry in 2016.Reference of 60979-25-1 This article mentions the following:

Silica-sulfuric acid efficiently catalyzes conversion of aliphatic, substituted aromatic and hetero aromatic nitriles to their corresponding amides in good to excellent yields under reflux condition. Products obtained were purified by column chromatog. method and characterized by 1H NMR, 13C NMR and mass spectral anal. In the experiment, the researchers used many compounds, for example, 3-Amino-4-methoxybenzonitrile (cas: 60979-25-1Reference of 60979-25-1).
