Reaction Steps
A mixture of 3-amino-5,5-dimethyl-4-phenyl-2(5H)-furanone (175 mg, 0.86 mmol), methyl 2-bromo-4-methylpentanoate (360 mg, 1.73 mmol) and cesium carbonate (310 mg, 0.95 mmol) in DMF (4 mL) was heated to 130° C. for 18 h. The mixture was cooled, diluted with EtOAc and washed with water (2×) and brine, then dried over MgSO4 and concentrated. Purification by flash chromatography (20% EtOAc/hexanes) provided methyl 2-[(5,5-dimethyl-2-oxo-4-phenyl-2,5-dihydro-3-furanyl)amino]-4-methylpentanoate.
