Reaction Steps
A mixture of (R)-2,5-dimethyl-2,3-dihydrobenzofuran (3d) (2.0 g, 13 mmol) in TFA (40 mL) was cooled to 0° C., NaNO2 (1.7 g, 23 mmol) was added thereto. It was stirred at ambient temperature for 12 h. The mixture was concentrated, poured into water (50 mL), extracted with EtOAc (150 mL), washed with brine, dried and concentrated. The residue was purified by column chromatography on silica gel eluting with hexanes/EtOAc (20:1) to give the title compound (3e).
