In 10 ml of ethanol, 0.32 g (13.9 mmol) of sodium was dissolved. Next, 2.36 g (8.96 mmol) of 4-dibutylamino-2-methoxybenzaldehyde and 1.58 g (9.39 mmol) of 2-methoxy-3,5,5-trimethyl-2-cyclohexenone were dissolved in ethanol and added to the mixture. The mixture was stirred with heating at 60° C. for 17 hours and concentrated. The residual liquid was purified by silica gel column chromatography to give 2.27 g of a dark red oily matter (yield: 61.2%).
