Pyridine → Methyl 4-(3-methyl-6-{[6-(1-methyl-1H-pyrazol-4-yl)-4-oxospiro[chroman-2,4'-piperidin]-1'-yl]carbonyl}-1H-indazol-1-yl)benzoate

Participants

Reaction Steps

Pyridine (0.080 ml, 0.988 mmol) was added to a stirred mixture of 1′-[(3-methyl-1H-indazol-6-yl)carbonyl]-6-(1-methyl-1H-pyrazol-4-yl)spiro[chroman-2,4′-piperidin]-4-one (150 mg, 0.329 mmol), [4-(methoxycarbonyl)phenyl]boronic acid (119 mg, 0.659 mmol), Cu(OAc)2 (90 mg, 0.494 mmol) in CH2Cl2 (1.5 ml) and the mixture was stirred at room temperature overnight. The mixture was filtered and the solvent was evaporated under reduced pressure. The residue was purified by silicagel column chromatography (hexane/EtOAc) to give intended compound as colorless oil.
