Procedure

To a stirred solution of 1-[4-(1-methylethenyl)phenyl]ethanone (711 mg, 4.44 mmol, trans) (Org. Lett., 2002, 4(1), 107-109), N-methylimidazole (1.06 ml, 13.3 mmol) and Co(TPP) (89 mg, 0.13 mmol) in toluene (10 ml) was added ethyl diazoacetate (0.65 ml, 6.21 mmol) in one portion at ambient temperature. The same procedure as described in Example 2H was performed to give the title compound (236 mg, 22%) as dark yellow oil.
