Potassium Carbonate → HCID 59820853, compound

Participants

Reaction Steps

A mixture of methyl N-[4′-(trifluoromethoxy)biphenyl-4-yl]oxamate (250 mg, 0.737 mmol), 3-methylbenzyl bromide (0.299 ml, 2.21 mmol), potassium carbonate (306 mg, 2.21 mmol), 18-crown-6 (20 mg, 0.074 mmol) and acetonitrile (10 ml) was stirred at 50° for 3 hors under argon atmosphere. The reaction mixture was cooled to room temperature, diluted with water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. The residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel (n-hexane:ethyl acetate=2:1) to give the title compound (320 mg, 98%) as a colorless oil.
