Procedure
Diispropylethylamine (300 μl) was added to a stirred solution of 5-phenyl-furan-2-carboxylic acid (73.5 mg, 0.39 mmol) and ethyl-4-aminophenyl acetate (70 mg, 0.39 mmoles) in N,N-dimethylformamide (10 ml). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (200 mg, 0.52 mmoles) was added and the solution was stirred at room temperature for 72 hours. The solvent was evaporated, the residue was dissolved in dichloromethane and washed with water, 10% aqueous sodium carbonate, 1 M aqueous hydrochloric acid and finally dried (MgSO4). After evaporation of the solvent, the residue was triturated with cyclohexane and dried to afford (1) (82 mg) as a gum. LC/MS System A; Rt=3.80 mins, m/z (ES+)=350 (M+H for C21H19NO4).
