Reaction Steps

24 mg (0.04 mmol) 4-{3-[5-(1,3-Dioxo-1,3-dihydro-isoindol-2-ylmethyl)-thiazol-2-ylamino]-benzylamino}-quinazoline-8-carboxylic acid amide trifluoroacetic acid salt were dissolved in 1 ml ethanol and treated with 10 μl (0.21 mmol) hydrazine hydrate. The mixture was stirred overnight at 50° C. in a closed vessel. Additional 40 μl hydrazine hydrate were added and the mixture was stirred at 60° C. for 24 h. The reaction mixture was evaporated and the crude product was purified using preparative HPLC. The product was treated with HCl in methanol and concentrated in the SpeedVac.
