1-Butanol → HCID 10397079, compound

A mixture of butanol (72.11 g, 1,000 mmol), methyl acrylate (129.14 g, 1,500 mmol) and DABCO (22.44 g, 200 mmol) is allowed to react at room temperature under N2 for 7 days. The reaction mixture is concentrated on Rotavap under reduced pressure (20 mbar) until no further solvent distills. The residue colorless liquid is dissolved in toluene (800 mL) and washed sequentially with 2 N HCl acid (250 mL), water (250 mL), saturated aq. sodium bicarbonate solution (120 mL) and water (150 mL). The toluene layer is concentrated on Rotavap under reduced pressure (20 mbar) until no further solvent distills to afford 3-hydroxy-2-methylenehexanoic acid methyl ester (96.7 g, yield: 61.1%) as a colorless liquid.
