Reaction Steps

A mixture of 1-iodobutane (185 mg) and zinc-copper couple (101 mg) in benzene (3 ml) and N,N-dimethylformamide (0.2 ml) was stirred at 60° C. for 2 hours. To the mixture, a solution of tetrakis(triphenylphosphine)palladium (31 mg) and 2-methoxy-4-(2-methyl-1-propenyl)benzoyl chloride (prepared from 138 mg of 2-methoxy-4-(2-methyl-1propenyl)benzoic acid and 0.07 ml of oxalyl chloride) in benzene (2 ml) was added, and the reaction mixture was stirred at room temperature for 30 minutes. The mixture was filtered and the filtrate was concentrated. The residue was dissolved in ethyl acetate and the organic solution was washed with water and brine, dried over magnesium sulfate and concentrated. The residue was chromatographed on silica gel column eluting with a mixture of hexane and ethyl acetate (9:1) to give 2'-methoxy-4'-(2-methyl-1-propenyl)valerophenone (91 mg) 10 as an oil.
