実験手順

The title compound was prepared as described in General Method 6 using 40 g (142 mmol) of 1-(4-benzyloxyphenyl)-4-methyl-pentan-3-one (prepared in Example F), 41.2 g (355 mmol) of methyl acetoacetate, 14.2 g (355 mmol) of 60% NaH dispersion in mineral oil, 216 mL (1.64M, 355 mmol) of n-butyllithium and 700 mL of THF. The reaction mixture was quenched with 0.1N HCl and the product was extracted into EtOAc. The organic layer was dried (MgSO4), and the solvents were evaporated.
