N-bromobutanimide → HCID 57963064, compound

Participants

Reaction Steps

To (6-fluoro-pyridin-2-yl)-(4-methoxy-benzyl)-amine (41, 151 g, 650 mmol) in 4 L of acetonitrile under an atmosphere of nitrogen, N-bromosuccinimide (116 g, 650 mmol) is added in portions. After reacting for 2 hours, the solvent is removed under vacuum and the residue is taken up in ethyl acetate, then poured into aqueous sodium thiosulfate. The organic layer is washed with warm water, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is crystallized from heptane to provide the desired compound (42, 172 g, 553 mmol, 85% yield).
