To a mixture of 1H-indole-4-carboxylic acid (322 mg, 2.00 mmol), tert-butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate (554 mg, 2.00 mmol), and diisopropylethylamine (700 μL, 4.00 mmol) in DMF (3 mL) was added HATU (950 mg, 2.50 mmol) and the solutions stirred for 16 h. The solvent was removed and the resulting residue was purified by silica gel chromatography, using a gradient of 70% to 100% EtOAc in hexanes as eluent and the solvent removed. This gave 557 mg (66%) of the product.
