- Novel commercial scale synthetic approach for 5-cyanoindole: A potential intermediate for vilazodone hydrochloride, an antidepressant drug
-
Present work describes the synthesis of 5-cyanoindole, a common intermediate used in various synthetic route of the antidepressant vilazodone hydrochloride. The protocol is both robust and commercially viable, utilizing readily available and low-cost materials and the isomers are environmental friendly than previously reported routes through its evading use of cyanide reagents and heavy metals.

- Mild and selective heterogeneous catalytic hydration of nitriles to amides by flowing through manganese dioxide
-
A sustainable flow chemistry process for the hydration of nitriles, whereby an aqueous solution of the nitrile is passed through a column containing commercially available amorphous manganese dioxide, has been developed. The product is obtained simply by concentration of the output stream without any other workup steps. The protocol described is rapid, robust, reliable, and scalable, and it has been applied to a broad range of substrates, showing a high level of chemical tolerance.
