Reaction Steps
To a solution of {3-[(5-chloro-4-{[3-(3-methoxyphenyl)propyl]amino}pyrimidin-2-yl)amino]phenyl}methanol (0.30 g, 0.75 mmol) in methylene chloride (4.8 mL) was added slowly a solution of boron tribromide in methylene chloride (3.8 mL, 1.0 M) at 0° C. The mixture was allowed to warm up to rt and stirred overnight. The resultant mixture was cooled in a dry ice bath when water was added. The mixture was allowed to warm up to rt. After methylene chloride layer was separated, water and EtOAc were added. The aqueous layer was extracted with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered, and concentrated (then triturated with cold EtOAc) to give the desired product as an off-white powder (252 mg, 75%).
