Participants

Reaction Steps

To a solution of methyl 2,3-bis(4-chlorophenyl)propionate (2.6 g, 8.4 mmol) in ether (20 mL) was added methylmagnesium bromide (3 M in ether, 8.4 mL, 25 mmol) at −10° C., and the reaction was allowed to warm to room temperature over 2 h. The reaction mixture was poured into saturated aqueous ammonium chloride (100 mL), and the product was extracted with EtOAc (3×100 mL). The combined extracts were dried over anhydrous MgSO4, filtered, and concentrated to dryness to give the title compound, which was used without further purification. 1H NMR (500 MHz, CD3OD): δ 7.17 (ABq, 4H), 7.06 (d, 2H), 6.93 (d, 2H), 3.32 (dd, 1H), 2.94 (dd, 1H), 2.84 (dd, 1H), 1.20 (s, 3H), 1.16 (s, 3H).
