Reaction Steps

To a 125 mL round-bottomed flask equipped with condenser and nitrogen inlet were added 486 mg (1.20 mmol) 3-phenyl-3-[4-(3-trifluoromethyl-phenoxy)-phenoxy]-1-chloropropane, 184 mg (1.20 mmol) sarcosine ethyl ester hydrochloride, 0.416 mL (2.40 mmol) diisopropylethylamine, and 6 mL dry N-methylpyrrolidinone. The reaction was heated at 90-95° C. for 60 h, cooled, and poured into water. After extracting with ethyl acetate, the organic layer was washed with water (3 times) and brine, dried over sodium sulfate, and evaporated. The residue was chromatographed on silica gel using methylene chloride/methanol as eluant to afford 250 mg (43%) of an oil.
