Procedure

A mixture of 1H-indol-6-ylboronic acid (43 mg, 0.27 mmol), 6-bromoquinolin-2-amine (40 mg, 0.22 mmol), K2CO3 (3M, 100 uL), PS—PPh3-Pd (20 mg, 0.11 mmol/g), and DME/EtOH (50%, 1 mL) was heated in a microwave at 140° C. for 10 min. The resulting slurry was filtered and purified by HPLC (10-60% CH3CN/water modified with 0.1% TFA) to give 6-(1H-indol-6-yl)quinolin-2-amine (31 mg). MS (ESI, pos. ion) m/z: 260 (M+1).

Workup

  1. filtrationThe resulting slurry was filtered
  2. custompurified by HPLC (10-60% CH3CN/water modified with 0.1% TFA)
