Reaction Steps

O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (0.66 g, 1.7 mmol), N,N-diisopropylethylamine (0.82 mL, 4.7 mmol) and 2-aminoethanol (0.14 mL, 2.4 mmol) were added to a solution of 5-bromo-2-furoic acid (0.30 g, 1.6 mmol) in dichloromethane (15 mL), and the mixture was stirred at room temperature overnight. After the reaction mixture was concentrated under reduced pressure, water (5 mL) was added thereto. The whole was extracted with ethyl acetate (10 mL), and the organic layer was washed with brine (5 mL) and dried over anhydrous magnesium sulfate. After the solvent was evaporated under reduced pressure, the residue was purified by silica gel column chromatography to give the title reference compound (0.18 g) as a colorless solid (yield 49%).
