A mixture of methyl 1-aminocyclopropane-1-carboxylate (0.50 g, 4.35 mmoles), powdered potassium carbonate (2.40 g, 17.4 mmoles), and tetrabutylammonium bromide (0.140 g, 0.43 mmoles) in anhydrous acetonitrile (12 mL) was treated with 1,5-diiodopentane (1.70 g, 5.22 mmoles). The mixture was stirred for three days at 90° C. The mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified on an Alltech pre-packed silica gel column eluting with ethyl acetate to afford the title compound. MS(DCI) m/z 184 (M+H)+. Vaidyanathan, G.; Wilson, J. W. J. Org.
