4-Heptanamine → HCID 49854109, compound

Participants

Reaction Steps

4-Heptylamine (2.5 g, 22 mmol) was added to a stirred solution of benzo[1,3]dioxol-5-yl-oxo-acetic acid ethyl ester (2 g, 9 mmol)) in ethanol (40 ml)) at room temperature. The resulting reaction mixture was heated to reflux for 4 hours. Then ethanol was distilled off and stirring was continued at 110° C. for 2 hours. The reaction mixture was cooled to room temperature and then 50 ml of THF and 100 ml of aqueous HCl solution were added and stirred for 30 minutes. The mixture was extracted twice with DCM (50 ml). The organic layer was washed twice with water (50 ml) and concentrated in vacuum. The crude product was chromatographed on a silica gel column using ethylacetate/heptane (2:3) as eluent to provide the title compound (0.5 g, 29% yield) as red crystals.
