3-Hydroxybenzaldehyde → HCID 21949743, compound

Participants

Reaction Steps

3-Hydroxybenzaldehyde (18.3 g, 0.150 mol) was dissolved in N,N-dimethylformamide (150 mL). Subsequently, potassium carbonate (22.80 g, 0.165 mol), and then ethyl 2-bromobutyrate (29.26 g, 0.150 mol) were added thereto, and the resultant mixture was stirred overnight at 80° C. The temperature of the reaction mixture was returned to room temperature. Ethyl acetate was added. Washing was performed sequentially with water and brine, followed by drying over sodium sulfate. The reaction mixture was subjected to filtration, concentration under reduced pressure, and purification by silica gel column chromatography (n-hexane/ethyl acetate=5/1), whereby a colorless oil was obtained (35.29 g, 0.149 mol, 99.6%).
