실험 절차

To a solution of methyl 3-cyclohexyl-1-[2-(dimethylamino)-2-oxoethyl]-2-formyl-1H-indole-6-carboxylate (from Step 4) in MeOH (0.05 M) was added K2CO3 (1.05 eq.) and tosylmethyl isocyanide (1.05 eq.). The resulting solution was refluxed under nitrogen for 1.5 h. The mixture was diluted with EtOAc and the organic phase was extracted with HCl (1N) and brine. The organic phase was then dried over Na2SO4 and evaporated in vacuo to give the clean product (quantitative).
