2-Bromo-1H-isoindole-1,3(2H)-dione (22.0 mg; 0.12 mmol) was added to a solution of 4-[2-(benzyloxy)-4-fluorophenyl]-5-fluoro-N-{3-[(methylsulfanyl)methyl]phenyl}pyrimidin-2-amine (37.0 mg; 0.08 mmol), cyanamide (4.5 mg; 0.11 mmol) and potassium 2-methylpropan-2-olate (11.1 mg; 0.10 mmol) in MeOH (0.44 mL) at RT. The batch was stirred for 4 hours before it was diluted with DCM and aqueous sodium thiosulfate solution. The batch was extracted with DCM (2×). The combined organic phases were filtered using a Whatman filter and concentrated to give crude (rac)-[[3-({4-[2-(benzyloxy)-4-fluorophenyl]-5-fluoropyrimidin-2-yl}amino)benzyl](methyl)-λ4-sulfanylidene]-cyanamide that was used without further purification.
