2,5-Dimethylbenzoxazole (cas: 5676-58-4) belongs to benzoxazole derivatives. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization. A number of marketed drugs are available having benzoxazole as core active moiety like, nonsteroidal anti-inflammatory drug (NSAID)—flunoxaprofen, benoxaprofen, antibiotic—calcimycin.HPLC of Formula: 5676-58-4

Indium-mediated one-pot synthesis of benzoxazoles or oxazoles from 2-nitrophenols or 1-aryl-2-nitroethanones was written by Lee, Jung June;Kim, Jihye;Jun, Young Moo;Lee, Byung Min;Kim, Byeong Hyo. And the article was included in Tetrahedron in 2009.HPLC of Formula: 5676-58-4 This article mentions the following:

One-pot reduction-triggered heterocyclizations from 2-nitrophenols to benzoxazoles and from 1-aryl-2-nitroethanones to oxazoles were investigated. In the presence of indium/AcOH in benzene at reflux, 2-nitrophenols and R-C(OMe)3 (R=H, Me, Ph) produced excellent yields of corresponding benzoxazoles within an hour. Similarly, 1-aryl-2-nitroethanones and Ph-C(OMe)3 in the presence of indium/AcOH in acetonitrile transformed into the corresponding oxazoles with good yields. In the experiment, the researchers used many compounds, for example, 2,5-Dimethylbenzoxazole (cas: 5676-58-4HPLC of Formula: 5676-58-4).
