N-bromobutanimide → (3-Bromo-1H-indol-5-yl)-(6-phenyl-thieno[3,2-d]pyrimidin-4-yl)-amine

Participants

Reaction Steps

To a solution of (1H-Indol-5-yl)-(6-phenyl-thieno[3,2-d]pyrimidin-4-yl)-amine (150 mg, 0.438 mmol) in methylene chloride was added N-bromosuccinimide (86 mg, 0.482 mmol). The reaction mixture was stirred for 2 days at room temperature and then concentrated in vacuo. The orange residue was chromatographed by preparative reverse-phase HPLC using a 200 nM acetate buffer and acetonitrile gradient to afford pure product (17% yield). RP18-HPLC RT: 6.377 minutes; API MS: 371.2 (M+1); MP: 201-203° C.
