3-甲基-3,9-二氮杂双环[4.2.1]壬烷

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Neat ammonium formate (2 g, 31.7 mmol) was added to stirred suspension of 9-benzyl-3-methyl-3,9-diazabicyclo[4.2.1]nonane (250 mg, 1.085 mmol) and 10% Pd-C (150 mg, 0.141 mmol) in abs. ethanol (50 ml). The mixture was heated to reflux for 2-3 h. The suspension was filtered and to the filtrate TFA (0.5 ml) was added and evaporated to dryness to afford 3-methyl-3,9-diazabicyclo[4.2.1]nonane and isolated as the bis-TFA salt. LC/MS: m/e 141 (MH+). The mixture was heated to reflux for 2-3 h The suspension was filtered and to the filtrate TFA (0.5 ml) was added evaporated to dryness
