Procedure
5-(Allyloxy)-1H-indole (514 mg, 2.97 mmol) (Example 53) was dissolved in 1,2,3,4-tetramethylbenzene (2.5 mL), and the reaction mixture was heated at 190° C. for 2 h. The mixture was cooled to rt and sonicated for 30 min. The mixture was then purified by silica gel column chromatography (EtOAc/hexane (v/v)=1:9) to give 361 mg (70%) of the title compound as a white crystalline solid. 1H NMR (400 MHz, CDCl3): δ 3.68 (d, 2H), 5.13 (d, 1H), 5.18 (d, 1H), 6.07 (m, 1H), 6.45 (s, 1H), 6.79 (d, 1H), 7.12-7.18 (m, 2H), 8.06 (br, 1H).
