Cs2CO3 (261 mg, 0.800 mmol), Pd(OAc)2 (8.98 mg, 0.040 mmol), 1-cyclopropyl-6-{[6-(1-methyl-1H-pyrazol-4-yl)-4-oxospiro[chroman-2,4′-piperidin]-1′-yl]carbonyl}-1H-indol-4-yl trifluoromethanesulfonate (251 mg, 0.4 mmol), ethyl 4-piperidinecarboxylate (94.0 mg, 0.600 mmol) and biphenyl-2-yl(di-tert-butyl)phosphine (11.9 mg, 0.0400 mmol) were suspended in 1,4-dioxane (3 ml) and the mixture was stirred at 100° C. overnight. The mixture was filtered through celite pad, washing with CHCl3, and the solvent was evaporated under reduced pressure. The residue was purified by silicagel column chromatography (CHCl3/MeOH), then preparative-TLC (CHCl3/MeOH) to give intended compound as brown oil.
