실험 절차

In a 250 mL round-bottomed flask was placed 3,3′-(6-(4-nitrophenyl)pyrimidine-2,4-diyl)bis(8-oxa-3-azabicyclo[3.2.1]octane) (22, 89 mg, 0.21 mmol) in ethanol (3 ml). A catalytic amount of Pd on charcoal (wet) was added and the mixture was stirred under a hydrogen atmosphere for 16 hours. The mixture was filtered over Celite™, rinsed with dichloromethane and concentrated to give a quantitative yield of the title compound along with an impurity (the N-ethyl aniline product). The crude mixture was reacted in the next step.
