YieldReaction ConditionsOperation in experiment
With palladium on activated charcoal; hydrogen; In ethanol; at 20℃; for 3.0h; To a stirred solution of 7-tert-butyl 2-methyl 3-bromo-7-azabicyclo[2.2.1] hepta-2,5- diene-2,7-dicarboxylate (15.0 g, 43.7 mmol, 1.0 eq) in ethanol (300 mL), was added palladium on carbon (2.0 g) and the reaction mixture was stirred at room temperature for 3 h under a hydrogen atmosphere maintained by a hydrogen filled balloon. After completion of the reaction (monitored by TLC, 10% ethyl acetate-hexane R = 0.5), the mixture was filtered through a celite pad, washing with methanol. The filtrate was evaporated under reduced pressure to obtain 7-tert- butyl 2-ethyl 7-azabicyclo[2.2.1]heptane-2,7-dicarboxylate (9.90 g, 85%) as a light brown oil. LCMS m/z = 255.25 (M-14) purity by 1H NMR >90%.
