Participants

Reaction Steps

A 50 mL round bottom flask, equipped with a thermometer, a stirrer and nitrogen inlet was charged with 3-(phenylmethoxy)-1,2,4-oxadiazol-5(4H)-one (0.5 g, 2.6 mmol), 1,8-diazabicyclo[5.4.0]unded-7-ene (0.5 g, 3.28 mmol), iodomethane (0.5 g, 3.54 mmol) and acetonitrile (5 mL). The mixture was stirred at room temperature for 18 h. To the mixture was added (4-chlorophenyl)(1-methylethyl)carbamic chloride (0.7 g, 3 mmol) and N,N′-dimethylamino-pyridine (0.367 g, 3 mmol), and the resulting mixture was heated to reflux for 2 h. It was then cooled to room temperature and flash chromatographed (silica gel, 9:1 hexane-ethyl acetate) to provide 150 mg (18%) of the title compound as a white solid melting at 121-123° C.
