Versuchsvorschrift

Bicyclic amine 49 (300 mg, 0.53 mmol) and TEA (150 μL) were dissolved in DCM (5 mL) at ambient temperature and benzyl isocyanate (135 μL, 1.06 mmol) was added. After 3 h, MeOH (20 mL) and 30% NH4OH (1 mL) were added and the solution was stirred for 15 min before being concentrated in vacuo. The residue was dissolved in EtOAc and washed successively with 1N HCl, water, aqueous NaHCO3, water, and brine. The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated to afford 450 mg of 50 as an amorphous solid which was used without further purification. Mass spectrum, m/z [702.3] (M+Na)+.
