2,4-Dihydroxybenzaldehyde → HCID 21841045, compound

Participants

Reaction Steps

Triethylamine (5 ml) was added to a stirred suspension of 2,4-dihydroxybenzaldehyde (12 g) in dichloromethane (50 ml) at -8° C. To this mixture was added t-butylcarbonyl chloride (4.4 ml) and the mixture was allowed to warm to ambient temperature and was stirred at this temperature for 16 hours. The reaction mixture was washed consecutively with aqueous 1N hydrochloric acid (20 ml), water (20 ml) and saturated aqueous sodium bicarbonate solution (20 ml) and then dried (MgSO4). The residue obtained on removal of the solvent was subjected to chromatography on silica eluting with a mixture of ethyl acetate and hexane (1:9 v/v) to give 4-(t-butylcarbonyloxy)-2-hydroxy-benzaldehyde (5.82 g; 35%).
