Reaction Steps

The same procedure as step 3 of example 1 was accomplished, except for using (2R,3S,4S)-8-nitro-2-methyl-2-dimethoxymethyl-3,4-epoxy-3,4-dihydro-2H-1-benzopyran (751 mg, 2.67 mmol) and N-(4-chlorophenyl)-N-(2-methyl-2H-tetrazol-5-ylmethyl)amine (597 mg, 2.67 mmol). The crude product was purified by silica gel column chromatography (developing solvent-n-hexane:ethyl acetate=2:1), to give desired compound (200 mg, yield: 15%).
