실험 절차
A mixture of 2-bromomethyl-5-phenyl-benzoxazole 49 (440 mg, 1.53 mmol) and cesium acetate (585 mg, 3.06 mmol) in 5 ml DMF was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate, washed with brine, dried, filtered and concentrated to yield acetic acid 5-phenyl-benzoxazole-2-ylmethyl ester 50.
