1,2-Dimethoxyethane → HCID 66991081, compound

Participants

Reaction Steps

Ethylene glycol dimethyl ether (0.90 mL), water (0.27 mL), 3-methoxyphenylboronic acid (0.030 g), sodium carbonate (0.044 g), and bis(triphenylphosphine)palladium(II) dichloride (2.3 mg) were added to methyl 2-(2-(benzyloxy)-5-(1-methylpiperidin-4-yl)benzamido)-4-bromobenzoate (0.090 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, washed with a saturated aqueous solution of sodium chloride, 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: 100-92% chloroform/methanol] to obtain 0.093 g of methyl 2-(2-(benzyloxy)-5-(1-methylpiperidin-4-yl)benzamido)-4-(3-methoxyphenyl)benzoate as a light brown solid.
