Triethylamine → 5H,6H,7H,8H,9H-pyrido[2,3-d]azepine

Participants

Reaction Steps

Under a hydrogen atmosphere 0.125 g (0.49 mmol) 2-chloro-6,7,8,9-tetrahydro-5H-pyri do[2,3-d]azepine, 30 mg palladium on charcoal (10%) and 0.28 mL triethylamine in 4 mL methanol were hydrogenated at RT under 50 psi hydrogen pressure for 6 h. The catalyst was removed and the filtrate was concentrated to dryness. The residue was used without further purification. Yield: 72 mg (99% of theory). ESI-MS: m/z=149 (M+H)+; Rt(HPLC): 0.52 min (Method J).
