Reaction Steps

A mixture of 2-(2,5-bis(hexyloxy)-4-(4-methylbenzo[d]oxazol-2-yl)phenyl)-5-(tert-butyl)benzo[d]oxazol (3.7 g, 6.35 mmol), N-bromosuccinimide (NBS) (1.13 g, 6.35 mmol), and AIBN (0.1 g, 0.6 mmol) in CCl4 (40 mL) was heated to reflux for 15 h under dry argon atmosphere. The reaction mixture was cooled to 0° C. and the precipitate was removed by filtration while maintaining the temperature at 0° C. After the solvent was evaporated, 4-(bromomethyl)-2-(4-(5-(tert-butyl)benzo[d]oxazol-2-yl)-2,5-bis(hexyloxy)phenyl)benzo[d]oxazole was obtained as an oil, which was used for next step without further purification.
