Triethylamine → HCID 21094291, compound

Participants

Reaction Steps

Copper acetate Cu(OAc)2 (960 mg; 5 mmol) and triethylamine (1.5 ml; 10.5 mmol) are suspended in 60 ml of dichloromethane. The compound of Example 4 (1 g; 3.5 mmol), 3-formylphenylboronic acid (1.05 g; 7 mmol) and molecular sieve are then added in succession and progressively to the solution. The reaction mixture is stirred at ambient temperature for 2 hours. The mixture is filtered, washed with water, dried over magnesium sulphate, filtered and evaporated under reduced pressure. The residue obtained is purified by chromatography on silica gel (eluant: dichloromethane with the progressive addition of methanol until the proportions 9/1 are reached) to yield the title product in the form of a yellow oil.
