Reaction Steps
To a solution of 1H-indole-4-carboxylic acid (250 mg, 1.55 mmol), 2-amino-indan-2-carboxylic acid ethyl ester (318 mg, 1.55 mmol), HATU (886 mg, 2.33 mmol) in anhydrous DMF (8 mL) is added DIPEA (385 μL, 2.33 mmol). The resulting solution is stirred at RT overnight. After the removal of DMF in vacuo, the residue is dissolved in EtOAc (40 mL) and washed with water (1×10 mL) and brine (2×10 mL). The organic layer is dried over anhydrous Na2SO4 and concentrated in vacuo. The residue is purified by flash column chromatography (115 g silica gel, gradient elution: 5-60% EtOAc in heptane) to give a pure product (55) as white solid (278 mg, 52%).
