1,2-Dimethoxyethane → HCID 66991010, compound

Participants

Reaction Steps

Ethylene glycol dimethyl ether (2.0 mL), water (0.60 mL), thiophene-2-boronic acid (0.054 g), sodium carbonate (0.093 g), and bis(triphenylphosphine)palladium(II) dichloride (4.9 mg) were added to tert-butyl 2-(2-(benzyloxy)-5-(morpholin-4-yl)benzamido)-4-bromobenzoate (0.20 g), followed by heating to reflux under a nitrogen atmosphere for 2 hours. The reaction mixture was cooled to room temperature, and water and ethyl acetate were added thereto. The organic layer was separated and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 85-70% hexane/ethyl acetate] to obtain 0.19 g of tert-butyl 2-(2-(benzyloxy)-5-(morpholin-4-yl)benzamido)-4-(thiophen-2-yl)benzoate as a light yellow solid.
