Reaction Conditions

Reaction Steps

A nitrogen gas was blown into a solution of 1-(4-chloro-2-methoxyphenyl)-2-methoxy-2-oxoethanediazonium (200 mg, 0.83 mmol) obtained in Example (74-1) in toluene (5 ml) at room temperature for 5 minutes. The reaction mixture was heated to 80° C. while blowing a nitrogen gas into the mixture and tetrakis(triphenylacetate)dirhodium (II) (1 mg) was added thereto, and the mixture was stirred for 15 minutes. The reaction mixture was cooled to room temperature and the residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (eluting solvent: n-hexane/ethyl acetate=5/1) to give the title compound as a pale yellow oil (127 mg, yield: 72%).
