Reaction Conditions

Reaction Steps

A suspension of Compound 61-1 (3.20 g) and chlorotris(triphenylphosphine)rhodium(I) (3.00 g) in toluene (70 ml) was stirred under a hydrogen atmosphere at 65° C. for 10 hr. The reaction mixture was concentrated, diisopropyl ether was added and the mixture was filtered through celite. The filtrate was concentrated and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=99:1-75:25) to give the object product (2.47 g) as a brown oil.
