Reaction Steps

A mixture of t-butyl 2-(p-bromophenylmethyl)indole-1-carboxylate (F) (6.0 g) (prepared, e.g., as described in Preparation 2), 10% sodium hydroxide in water (20 ml), and ethanol (150 ml), was heated under reflux for 6 hours. The mixture was then poured onto a mixture of ice water/dilute brine and extracted twice with ethyl acetate. The extract was washed with brine and dried over magnesium sulphate. The solvent was evaporated under reduced pressure to produce an oil, which then crystallized. The material was recrystallized from methyl t-butyl ether to give 2-(p-bromophenylmethyl)indole (2.2 g), a compound of Formula (G), m.p. 136° C.
