Reaction Steps

The same procedure as step 3 of example 1 was accomplished, except for using (2R,3S,4S)-6-methane sulfonyloxy-2-methyl-2-dimethoxymethyl-3,4-epoxy-3,4-dihydro-2H-1-benzopyran (231 mg, 0.70 mmol) and N-(4-chlorophenyl)-N-(2-methyl-2H-tetrazol-5-ylmethyl)amine (187 mg, 0. 84 mmol). The crude product was purified by silica gel column chromatography (developing solvent-n-hexane:ethyl acetate=1:1), to give desired compound (104 mg, yield: 27%).
