Reaction Steps

The intermediate product, reported in J. Med. Chem., 1998, 41/10, 1619-1639, was prepared according to the procedure described therein, with the exception of the duration of the reaction time (equal to 30 hours instead of 30 minutes), starting from indole (5.0 g, 42.7 mmol), KOH (3.6 g, 64.1 mmol) and bromoethanol (6.4 g, 51.3 mmol) in 50 ml of anhydrous DMSO, at a temperature of 25-30° C., to obtain 5 g of oily product (yield: 73%).
