実験手順

A solution of 100 millimols (15.2 g) of camphor in 250 ml of toluene is heated for 1 hour at the boil with 100 mmols (5.4 g) of sodium methylate. After cooling, 100 mmols (17.8 g) of p-butoxybenzaldehyde are introduced and the mixture is heated at the reflux temperature for 4 hours. The reaction mixture is cooled and 50 ml of water are then added; the toluene phase is separated off, washed with water, dried over sodium sulphate and concentrated to dryness. The solid residue is crystallised from aqueous isopropanol. After drying, 12 g of a white owder, which melts at 62°, are collected.
