Procedure
(2,6-Dichloro-3,5-dimethoxy-phenyl)-[3-(6-methanesulfinyl-pyrimidin-4-yl)-pyrazin-2-yl]-amine 7 (200 mg, 0.414 mmol) is suspended in ammonia/2-propanol solution (2M, 3 mL, 6 mmol) in a sealed tube. After stirring at 100° C. overnight, the reaction is cooled to room temperature. The light yellow solid is collected by filtration, washed with water and 2-propanol, and dried to afford the desired product (6-[3-(2,6-dichloro-3,5-dimethoxy-phenylamino)-pyrazin-2-yl]-pyrimidin-4-ylamine (40). The filtrate can be used for further purification to give an additional product.
