Participants

Reaction Steps

To a solution of tert-butyl 4-{(1E)-3-[5-(diphenylmethyl)-2-oxo-1(2H)-pyridinyl]-1-propen-1-yl}-1H-indole-1-carboxylate (247 mg) in MeOH (5 mL) was added 1M NaOH aqueous solution (1.5 mL) at ambient temperature. The reaction mixture was stirred for 17 hours at ambient temperature. The resulting mixture was diluted with EtOAc (15 mL) and washed successively with water and brine. The organic layer was dried over anhydrous MgSO4, filtered and evaporated in vacuo. The residue was purified by silica gel column chromatography (n-hexane:EtOAc=80:20-50:50) to give 5-(diphenylmethyl)-1-[(2E)-3-(1H-indol-4-yl)-2-propen-1-yl]-2(1H)-pyridinone.
