Procedure

A mixture of 4-[(5E)-5-(5,6-difluoro-2-oxo-1,2-dihydro-3H-indol-3-ylidene)-2,2-dimethyl-2,5-dihydrofuran-3-yl]benzoic acid (50 mg, 0.13 mmol), 3-methylamino-1,2-propanediol (40 mg, 0.38 mmol), O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HBTU, 61 mg, 0.16 mmol) and diisopropylethylamine (37 mg, 0.29 mmol) in 6 mL of anhydrous DMF was stirred at room temperature for 10 minutes. The mixture was poured into 100 mL of water. The precipitates were filtered, washed with water, and dried in vacuum to give 4-[(5E)-5-(5,6-difluoro-2-oxo-1,2-dihydro-3H-indol-3-ylidene)-2,2-dimethyl-2,5-dihydrofuran-3-yl]-N-(2,3-dihydroxypropyl)-N-methylbenzamide as yellow solid. Yield: 47 mg, 81%.
