実験手順
To a suspension of Zn/Cu couple (3.24 g) and dry ether (20 ml) was added to the compound of formula (7), (2 g, 0.0075 mol) in ether (10 ml) followed by the addition of diiodomethane (4.2 ml, 0.052 mol). The reaction mixture was refluxed under nitrogen atmosphere for 72 h (monitored by TLC) and filtered. The filtrate was washed with water, dried, concentrated and the residue purified by column chromatography on silica gel, eluting with light petroleum ether:ethyl acetate(2:50) to afford pure product of formula (8), as an oil 1.8 g (85%).
