PROCEDURE

实验过程

6-Hydroxy-2-naphthoic acid (30 g, 160 mmol, Aldrich), dppa (48.4 g, 176 mmol, Aldrich), benzyl alcohol (51.8 g, 480 mmol, Aldrich) and Et3N (32.3 g, 320 mmol, Aldrich) were heated at reflux with toluene (500 mL, Aldrich) for 16 h. After cooling to RT, the volatile portion was removed in vacuo. The resulting brown residue was purified by silica gel column chromatography (40% EtOAc/hexane) to give crude compound, which was further purified by crystallization from 50% EtOAc/Hexane to give the title compound as an off-white solid. MS (ESI, pos. ion) m/z: 294.2 (M+1). Mass Calc'd for C18H15NO3: 293.11.
