4-Hydroxybenzaldehyde → HCID 21703917, compound

Participants

Reaction Steps

To a solution of 2-isopropoxyethanol (600 mg, 5.76 mmol), p-hydroxybenzaldehyde (0.78 g, 6.34 mM) and triphenylphosphine in THF (20 ml) (1.6 g, 6.1 mmol), diethyl azodicarboxylate (40% in toluene) was added at 0° C. over 10 minutes while stirring. Then, the mixture was stirred at room temperature for 18 hours until the initial reaction product of 2-isopropoxyethanol and p-hydroxybenzaldehyde disappeared. The resulting solution was concentrated and purified by silica gel chromatography (hexane:ethylacetate=5:1) to obtain 4-(2-isopropoxyethoxy)benzaldehyde as yellow oil (0.98 g, yield: 82%).
