Versuchsvorschrift

To a stirred solution of N-(4-chloro-6-(phenylamino)pyrimidin-5-yl)benzamide obtained in step 2 (35 g, 108 mmol) in 2-propanol (360 mL) was added sulfuric acid (18.2 mL, 323.3 mmol) at 0° C. The reaction mixture was heated to reflux at 90° C. overnight. After cooled to room temperature NaHCO3 (aq) was added to the resulting reaction mixture and stirred. The resulting mixture was filtered with water (600 mL). The collected solid was dried under reduced pressure to obtain the title compound (22.3 g, 72%) as white solid.
