Participants

Reaction Steps

To a 0.3M solution of methyl 3-cyclohexyl-2-(2-vinylphenyl)1H-indole-6-carboxylate in dry DMF, 60% NaH (1.5 eq) in mineral oil was added at 0° C., after 1 h allyl bromide (1.5 eq) was added and the suspension was stirred at RT for 2 h. The mixture was diluted with EtOAc, washed with 1N HCl, water and brine, dried over Na2SO4 and concentrated in vacuo to give the title compound (100% as crude); MS (ES+) m/z 400 (M+H)+.
