Reaction Steps

To a solution of 1-(4-bromobenzyl)-1H-indole-5-carboxylic acid (1.03 g, 3.1 mmol, 1 equiv) in DMF (30 mL) were added the (S)-1-(4-nitrophenyl)ethanamine hydrochloride (695 mg, 3.4 mmol, 1.1 equiv), DIEA (600 μL, 3.4 mmol, 1.1 equiv), HOBt (525 mg, 3.4 mmol, 1.1 equiv) and EDC (658 mg, 3.4 mmol, 1.1 equiv). After stirring 4 h at room temperature, the mixture was diluted with AcOEt and washed with a 0.5 N HCl aqueous solution, a saturated NaHCO3 solution and brine, dried over MgSO4 and concentrated in vacuo. The crude was purified by flash chromatography (Hexane/AcOEt 1/1) to afford a yellow powder (1.3 g, 2.7 mmol, 87%). ESI-MS (m/z): 478/480 [M+H]+.
