The resulting mixture was heated at 65° C. for 18 hours. After cooling to room temperature water (3 mL) was added, extracted with EtOAc, washed with brine, dried over MgSO4, and then purified by MPLC (gradient: Hex to EtOAc) to give 0.16 g of the titled compound as an inseparable mixture with 4-(1H-Indol-3-yl)butan-1-ol. It was intended to obtain an ether, but the reaction converted the Br to OH; 1H NMR (400 MHz, CDCl3) δ 9.70 (s, 1H), 7.54 (s, 1H), 7.27-7.2 (m, 2H), 7.04 (s, 1H), 6.87 (d, J=7.0 Hz, 1H), 5.79 (s, 2H), 4.65 (s, 2H), and 3.77 (s, 2H).
