Reaction Steps
To a mixture of isovanillic acid methyl ester (33.0 g, 0.18 mol) and potassium carbonate (41.4 g, 0.30 mol) in DMF (100 ml) was added a solution of trifluoroethyl triflate [Burdon et al Tetrahedron 21, 1 (1965)] (65.0 g, 0.28 mol) in CH2Cl2. The mixture was stirred at room temperature for 18 h then evaporated to 50 ml, the mixture partitioned between ether and H2O, the organic layer washed with H2O and saturated brine, then dried over MgSO4 and evaporated. The resulting solid was triturated with hexane to give the subtitle compound as an off-white solid (42.55 g, 90%). Rf 0.47 (CH2Cl2). MS m/z 265 (MH+).
