Versuchsvorschrift

To a stirred and cooled (0° C.) solution of triphosgene (0.80 g, 2.7 mmol) in THF (20 mL) was added, dropwise, a mixture of (3-bromophenyl)methanamine (1.0 g, 5.4 mmol) and triethylamine (1.08 g, 10.7 mmol) in THF (30 mL) over 2 h. After the addition was complete, the mixture was refluxed for 1 h and then cooled to room temperature. Quinuclidin-3-ol (1.40 g, 10.7 mmol) was added, and the mixture was refluxed for 18 h. The solvent was removed in vacuo, and the residue was dissolved in EtOAc, washed with water, dried over Na2SO4, and concentrated. The crude residue was purified by silica gel column chromatography (eluting with EtOAc/methanol=10/1) to give quinuclidin-3-yl 3-bromobenzylcarbamate as a colourless liquid (0.68 g, 37%).
