Pyridine → HCID 76803837, compound

Participants

Reaction Steps

Add O-methylhydroxylamine hydrochloride (10 mg, 0.12 mmol) and pyridine (0.02 mL, 0.24 mmol) to a solution of 6-(4-acetyl-benzylamino)-7-chloro-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (50 mg, 0.12 mmol) in ethanol (10 mL). Heat the mixture to reflux for 1.5 h. Remove the solvent in vacuo and partition the residue between DCM and 0.1N aqueous HCl. Dry the organic phase over Na2SO4, filter and concentrate in vacuo. Purify by chromatography on silica gel eluting with hexane/EtOAc (95:5 to 1:1 gradient over 30 min). Concentrate in vacuo to obtain 7-chloro-6-[4-(1-methoxyimino-ethyl)-benzylamino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as a colorless oil (45 mg, 83%). MS (ES+) m/z: 454 (M+H)+.
