Reaction Steps

To a solution of 6-bromo-2-(3-methoxyphenyl)benzoxazole (Compound of Example 242) (19.45 g) in chloroform (800 ml) was added dropwise boron tribromide (100.05 g) at 0° C., and the mixture was stirred at room temperature for 4 hours and 65° C. for 9 hours. The reaction mixture was poured into water, and the mixture was stirred at room temperature for 30 minutes and extracted with chloroform-tetrahydrofuran (4:1, v/v). The organic layer was washed with water and dried over MgSO4, and the solvent was distilled off under reduced pressure. The resulting crystals were collected by filtration to obtain 3-(6-bromobenzoxazol-2-yl)phenol (16.46 g, 89%).
