To a stirred solution of 5.00 g (42.7 mmol) of indole in 10 mL of DMSO was added 10.8
g (192 mmol) of crushed KOH. Addition of 12.9 g (85.4 mmol) of 1-bromopentane was
followed by stirring at ambient temperature for 1.5 h under N2. The reaction was
quenched with water and the product was extracted with 3 portions of dichloromethane.
The organic layer was dried (MgSO4) and concentrated in vacuo. Kugelrohr distillation at
200 ¡ÆC under 19 in. Hg gave 8.15 g (98%) of N-pentylindole as a green oil:
