6-Chloro-2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (0.5 g, 2.27 mmol), sodium tert-butoxide (1.30 g, 1.36 mmol), palladium acetate (0.101 g, 0.453 mmol) and 2-di-tert-butyl-phosphino-2′-4′-6′-triisopropyl-biphenyl (0.192 g, 0.45 mmol) were mixed in a reaction bottle which was evacuated and back filled with nitrogen for 5 min. Dry toluene (3 mL) was added under a nitrogen atmosphere. (Pyridin-4-yl)methanamine (291 mg, 2.72 mmol) was added and the mixture was heated at 85° C. overnight. The reaction mass was filtered and washed with EtOAc (2×25 mL). The filtrate was concentrated under vacuum and the residue purified on neutral alumina using 0-10% MeOH:EtOAc as eluent. Yield: 180 mg (freebase).
