Reaction Steps

To a solution of methyl 2-bromo-3-cyclohexyl-1H-indole-6-carboxylate (prepared as described in WO 2004087714 from commercially available methyl indole-6-carboxylate) in MeCN (0.08 M) were added 6 eq of K2CO3 and 1.2 eq of methyl 2-[bis(tert-butoxycarbonyl)amino]acrylate. The mixture was stirred at RT for 16 h before being filtered and concentrated in vacuo to afford the title compound as a viscous oil which solidified on standing (quantitative); MS (ES+) m/z 659 (M+Na)+, 661 (M+Na)+.
