9-cyclopropyl-9-azabicyclo[3.3.1]nonan-3-amine

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 70 mg of 8-[(2,6-difluorobenzyl)oxy]-2-methylimidazo[1,2-a]pyridine-3-carboxylic acid (0.22 mmol), 209 mg of O-(7-azabenzotriazol-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (HATU, 0.55 mmol) and 85 mg of N,N-diisopropylethylamine (0.66 mmol) were initially charged in 1.5 ml of DMF and stirred for 15 min. 59 mg of 9-cyclopropyl-9-azabicyclo[3.3.1]nonane-3-amine (0.33 mmol) were added, and the mixture was stirred at RT overnight. The mixture was then stirred overnight once more, at 60° C. 12 ml of water were added to the reaction solution, and the precipitate formed was filtered off, washed with water and dried. The residue formed was purified by silica gel chromatography (mobile phase: dichloromethane/methanol 40:1). This gave 60 mg of the title compound (53% of theory, purity 94%). the mixture was stirred at RT overnight The mixture was then stirred overnight once more at 60° C the precipitate formed was filtered off washed with water dried The residue formed was purified by silica gel chromatography (mobile phase: dichloromethane/methanol 40:1)
