実験手順

A solution of a mixture of compound (1e) (0.560 g), trans-4-hydroxycyclohexylamine (0.522 g), sodium tert-butoxide (0.218 g), palladium acetate (0.025 g), and 1,1-bis-(diphenylphosphino)-ferrocene (0.126 g) in 1,4-dioxane (12 mL) was stirred under a nitrogen atmosphere at 140° C. for 2 hr. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with saturated saline. The organic layer after the washing was dried over anhydrous sodium sulfate, and then the solvent was distilled away. The residue was purified by neutral silica gel column chromatography (chloroform/methanol) to obtain compound (1f) (0.450 g, 75%) as a white solid.
