Facile Synthesis of (S)‐2‐Aryl‐N‐(1‐phenylethylisonicotinamides) Derivatives via SMC Reaction: Their Thermodynamic and Spectroscopic Features via DFT Approach

Abstract

In this study, 2‐bromoisonicotinic acid and (S)‐1‐phenylethaneamine were reacted in the presence of pyridine and TiCl4 to produce 2‐bromo‐N‐(1‐phenylethyl)isonicotinamide (3). The derivatives (5a–f) of (S)‐2‐bromo‐N‐(1‐phenylethyl)isonicotinamide were then created by a Suzuki–Miyaura cross‐coupling process catalyzed by palladium (0) and K3PO4 as a base. The reactivity and electronic features of the compounds were investigated using DFT molecular electrostatic potential investigations, reactivity descriptors, and frontier molecular orbital analysis.
