実験手順

Methyl chloroacrylate (1.7 eq.), triethylbutyl ammonium chloride (0.2 eq.) and K2CO3 (6 eq.) were added to a solution of methyl 3-cyclohexyl-2-(2-hydroxyphenyl)-1H-indole-6-carboxylate (prepared as described in International patent application publication W02006/046030, Example 9) in anhydrous MeCN (0.02 M). The mixture was heated at 60° C. overnight and then allowed to cool to RT. Volatiles were removed in vacuo, diluted with EtOAc, washed with water, dried (Na2SO4), filtered and concentrated in vacuo. The crude product was purified by FC (EtOAc/PE 10:90) to afford the product as a solid (81%). (ES+) m/z 434 (M+H)+.
