Reaction Steps

A high-pressure vial was filled with the (S)-1-(4-bromobenzyl)-N-(1-(4-nitrophenyl)ethyl)-1H-indole-5-carboxamide (50 mg, 0.1 mmol, 1 equiv), the phenylboronic acid (19 mg, 0.15 mmol, 1.5 equiv), K2CO3 (29 mg, 0.2 mmol, 2 equiv), Pd(PPh3)4 (12 mg, 0.01 mmol, 0.1 equiv), dioxane (1.5 mL) and water (0.3 mL). The mixture was degassed for 5 min under argon atmosphere and the vial was sealed. The reaction mixture was heated at 100° C. for 30 min under microwaves. The solution was then concentrated in vacuo, filtered and purified by preparative HPLC to afford a beige powder (50 mg, 0.1 mmol, 100%). ESI-MS (m/z): 476 [M+H]+.
