実験手順

Benzyl amine (1.7 mL, 1.1 eq) was added to a solution of rac-1-oxa-5-aza-spiro[2.4]heptane-5-carboxylic acid tert-butyl ester (commercial, 2.80 g, 14.05 mmol) in MeOH (25 mL) and the mixture was heated at reflux for 2 h. The resulting solution was concentrated under reduced pressure and the residue was purified by CC (DCM-MeOH—NH4OH 1000:50:4) to afford the title compound as colourless oil (4.29 g, 100%).
