80 °C

A mixture of methyl 2-ethyloxirane-2-carboxylate (1.9 g, 15 mmol) and cyclopentylamine (2.2 mL, 22 mmol) in ethanol (50 mL) was heated at 80° C. for 3 d. The reaction mixture was then concentrated, diluted to EtOAc, washed by NaHCO3, brine and water. Organic layer was dried, concentrated to give a residue which is used for next step without further purification (2.7 g, 80%). [M+H] calc'd for C12H23NO3, 230; found 230.
