Participants

Reaction Steps

To a solution of 3-{(2R)-2-[2-(3-chlorophenyl)-(2R)-2-hydroxy-ethylamino]propyl}-1H-indole-7-carboxylic acid diethylamide.hydrochloride (47 mg, 0.1 mmol) and triethylamine (139 μL, 1 mmol) in tetrahydrofuran (3 mL) is added triphosgene (12 mg, 0.04 mmol), and the mixture is stirred at room temperature for 4 hours. To the mixture is added a saturated aqueous sodium hydrogen carbonate solution, and the mixture is extracted with ethyl acetate. The organic layer is washed with a saturated brine, dried over sodium sulfate, and concentrated. The residue is purified by silica gel column chromatography (methanol/chloroform=1/50) to give 3-{(2R)-2-[(5R)-5-(3-chlorophenyl)-2-oxooxazolidin-3-yl]propyl}-1H-indole-7-carboxylic acid diethylamide (45 mg, yield: 100%).
