Abstract:The novel scaffold of 3-ethyl-6-methoxybenzo[d]isoxazole-5-amine(1) was synthesized in five steps including amidation, Friedel-Crafts acylation, oximation, cyclization and hydrolyzation using 2,4-dimethoxyaniline as the starting material. The reaction mechanism of the key step was analyzed, the synthetic method was screened and the post-processing operation was optimized. The method had the advantages of easy availability of raw materials, simple operation and high yield. The target compound was confirmed by 1H NMR, 13C NMR, MS and IR. In addition, molecular docking and drug-like calculations showed that compound 1 could effectively bind to the BRD4 bromodomain pocket and possessed good drug-like properties.
Key words:3-ethyl-6-methoxybenzo[d]isoxazol-5-amine; Friedel-Crafts reaction; drug-likeness; BRD4 inhibitor
