Procedure: Ethyl 2-carboethoxy-4[4'-(4"-chlorophenyl) phenyl]-4-oxobutanoate (0.40 g, 1.02 mmol) was added in one portion at rt to a solution of sodium ethoxide (0.08 g, 1.12 mmol) in DME (1 mL). After 15 min, 4-phenyl-1-iodobutane (0.24 g, 0.93 mmol) in DME (3 mL) was added. The resulting solution was stirred for 18 h. The solvent was concentrated in vacuo and the resulting oil dissolved in CH2Cl2 (100 mL) and washed with water (100 mL). The phases were separated and the aqueous phase was extracted with CH2Cl2 (2×50 mL). The combined organic phases were dried (MgSO4), filtered, and concentrated in vacuo. The resulting oil was purified by flash chromatography on silica gel using a gradient of ethyl acetate/hexane (10% to 25% ethyl acetate) as the eluent to afford a crystalline solid which was recrystallized with hexane and ethyl acetate to afford 1-[4'-(4"-chlorophenyl)phenyl]-3,3-dicarboethoxy-1-oxo-7-phenylheptane (0.272 g, 28%). The solvent was concentrated in vacuo the resulting oil dissolved in CH2Cl2 (100 mL) washed with water (100 mL) The phases were separated the aqueous phase was extracted with CH2Cl2 (2×50 mL) The combined organic phases were dried (MgSO4) filtered concentrated in vacuo The resulting oil was purified by flash chromatography on silica gel using a gradient of ethyl acetate/hexane (10% to 25% ethyl acetate) as the eluent to afford a crystalline solid which was recrystallized with hexane and ethyl acetate

Procedure: Sodium iodide (8.9 g, 59.2 mol) and 4-phenyl-1-chlorobutane (5.0 g, 29.6 mol) were added to acetone (29.6 mL) at rt. The mixture was heated to 70° C. for 12 h. The resulting solution was gravity filtered to remove salts. The solvent was removed under reduced pressure and excess salts were dissolved in water (100 mL). Hexane (100 mL) was added to the aqueous mixture. The phases were separated and the organic phase was washed with saturated sodium bisulfite solution (3×50 mL), treated with decolorizing carbon, and gravity filtered.
