p-Toluenesulfonic acid → 7-nitro-1H-indene

참여 물질

반응 단계

A solution of 4-nitroindan-1-ol (0.385 g, 2.15 mmol) and p-toluenesulfonic acid (5.0 mg, 0.03 mmol) in toluene (30 ml) was stirred and heated to reflux for 16 hours. After cooled to ambient temperature, the mixture was washed with aqueous sodium bicarbonate solution. The organic layer was dried over MgSO4, filtered, and concentrated under reduced pressure. The obtained residue was purified by preparatory TLC (hexane:ethylacetate 3:1) to afford 7-nitro-1H-indene (0.289 g).
