Triphenylphosphine → HCID 59497686, compound

Participants

Reaction Steps

To a solution of 1-isopropenylbenzimidazolone (1.0 g, 5.7 mmol) in dry THF (80 mL) are added triphenylphosphine (1.8 g, 6.9 mmol) and naphthalen-1-yl-methanol (1.1 g, 6.9 mmol). Then diisopropyl azodicarboxylate (1.4 mL, 6.9 mmol) is added drop wise into the above solution at room temperature. The mixture is stirred for 16 hrs and then the solvent is removed under vacuum. The residue is purified by flash column chromatography using 10% EtOAc in hexanes to give 1.6 g (89%) of 1-isopropenyl-3-naphthalen-1-ylmethyl-1,3-dihydro-benzimidazol-2-one.
