| Product | 4-(Hexyloxy)-2-hydroxybenzaldehyde | HCID 13147236 | 37% |
Reaction Steps
2,4-Dihydroxybenzaldehyde (3.00 g, 21.7 mmol) and hexyl bromide (7.62 ml, 54.3 mmol) were stirred in the presence of lithium carbonate (4.00 g, 54.3 mmol) in dimethylformamide (5 ml) at 55° C. overnight. After the neutralization with hydrochloric acid followed by the extraction with ethyl acetate, the product was purified by the silica gel column chromatography to obtain 4-hexyloxy-2-hydroxybenzaldehyde (yield: 1.77 g, 37%) in the form of a colorless oil.
