Reaction Steps
To a solution of 4-[2-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthoxy)ethoxy]benzaldehyde (1.50 g, 4.26 mmol) and dimethyl malonate (1.69 g, 12.78 mmol) in toluene (30 ml) is added a catalytic quantity of piperidinium acetate. Then the mixture is refluxed in a Dean-Stark trap for 8 hours. After cooled to room temperature, the solution is concentrated under a vacuum to give title compound (1.95 g, 98%).
