実験手順

Into a 1 l. r.b. flask equipped with a Dean-Stark trap was placed 79 g (0.2 mole) of 1-(3',4'-dimethoxyphenyl)-7-(4'-fluorophenyl)-2-nitro-5-heptanone, 38 g p-toluenesulfonic acid, 120 ml ethylene glycol and 400 ml cyclohexane. The mixture was allowed to reflux overnight, then concentrated in vacuo. Dil NaHCO3 solution was added to the residue and extracted with methylene chloride. The organic layer was backwashed with water, dried over anh MgSO4, filtered and concentrated under reduced pressure to obtain 84.8 g of oily product.
