8-Methyl-8-azabicyclo(3.2.1)octan-3-ol → HCID 25109111, compound

Participants

Reaction Steps

8 mL of dry dichloromethane were added to 814 mg (1.73 mmol) of polystyrene bound triphenyl phosphine. At 0° C. 234 μL (1.48 mmol) of diethyl azodicarboxylate were added. 200 mg (1.24 mmol) of 6-hydroxy-2H-isoquinolinone (66), 210 mg (1.49 mmol) of tropine and 261 μL of triethylamine were added and the reaction mixture was allowed to warm to room temperature and stirred overnight. Another 279 mg of PS-triphenyl phosphine, 43 mg of tropine, 26 μL of diethyl azodicarboxylate and 2 mL of dry dichloeomethane were added and stirring was continued overnight. The solids were filtered off and washed with THF. The mixture was evaporated and purified by flash chromatography to give 158 mg of 6-(8-methyl-8-aza-bicyclo[3.2.1]oct-3-yloxy)-2H-isoquinolin-1-one (53). Rt=0.79 min (Method B). Detected mass: 279.2 (M+H+).
