実験手順

Under a nitrogen atmosphere, phenyl isocyanate (0.056 mL, 0.515 mmol) was added to a suspension of 5′-aminospiro[1-azabicyclo[2.2.2]octane-3,2′(3′H)-furo[2,3-b]pyridine] (119 mg, 0.514 mmol) in anhydrous tetrahydrofuran (5 mL) and stirred for 12 hours. The solvent was evaporated under reduced pressure and the residue purified by flash chromatography through silica gel, eluting with ammoniated chloroform/methanol (92.5:7.5), to obtain the title compound (155 mg, 0.442 mmol, 86%) as an off-white solid: electrospray MS (m/z, relative intensity) 351 ([MH]+, 100).
