Reaktionsschritte
Commercially available p-hydroxybenzaldehyde (50 g) was dissolved in pyridine (400 ml), followed by dropwise adding octyl chloroformate (85 g) under ice cooling, heating on a water bath, allowing the reaction mixture to stand overnight, adding toluene (300 ml) and 6N hydrochloric acid, separating the liquid layer, further washing with an aqueous solution of 2N NaOH, washing with water, drying and distilling off toluene to obtain a raw product of p-octyloxycarbonyloxybenzaldehyde (75 g).
