反応手順
4-hydroxy-3-methoxybenzoic acid (25 g, 150 mmol) and 2-amino phenol (16 g, 150 mmol) were combined in a round bottom flask. Trimethylsilyl polyphosphate (80 mL) was added. The mixture was heated at 180° C. for 30 min. The mixture was poured over ice and allowed to stir overnight. The suspension was filtered to afford 4-(1,3-benzoxazol-2-yl)-2-methoxyphenol as a pale green solid. MS (ESI) 242 (M+H).
