Participants

Reaction Steps

Add hydroxylamine hydrochloride (6.3 mg, 0.091 mmol) and pyridine (15 uL, 0.182 mmol) to a solution of 7-chloro-6-[4-(3-methyl-butyryl)-benzylamino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (42 mg, 0.091 mmol) in ethanol (1 mL). Heat the mixture to reflux for 18 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-hydroxyimino-3-methyl-butyl)-benzylamino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as an off-white solid (19.1 mg, 44%). MS (ES+) m/z: 482 (M+H)+.
