Procedure

Using general procedure A, 2-azetidinone (88 mg, 1.24 mmol) was coupled with 5-iodo-m-xylene (150 μL, 1.04 mmol). The crude product was purified by flash chromatography on silica gel (2×15 cm; hexane-ethyl acetate 1:1; 15 mL fractions). Fractions 5-10 provided 173 mg (95% yield) of the product as a white solid. 1H NMR (400 MHz, CDCl3): δ 7.01 (s, 2H), 6.76 (s, 1H), 3.61 (t, J=4.5 Hz, 2H), 3.10 (t, J=4.5 Hz, 2H), 2.32 (s, 6H).
