How is 4-[(E)-(4-Carbamoylphenyl)diazenyl]-3-hydroxy-N-(2-methoxyphenyl)-2-naphthamide (CAS: 36968-27-1) typically synthesized?

This compound is usually synthesized through a multi-step process involving diazotization, coupling, and amidation reactions. Commonly, a diazo compound derived from 4-carbamoylphenyl is combined with 2-naphthamide and a 2-methoxyphenyl group under basic conditions. The reaction typically uses sodium hydroxide or potassium hydroxide as a catalyst, with high selectivity and yield, making it a viable method for producing this compound in the laboratory.
