Reaction Steps
A 4 ml portion of 4 M hydrochloric acid-dioxane solution was added to 183 mg of tert-butyl ester of {4-[5-carbamoyl-4-(3-methylanilino)pyrimidin-2-ylamino]benzyl}carbamic acid, followed by stirring at room temperature for 16 hours. Water and ethyl acetate were added to the reaction mixture, the thus formed insoluble matter was removed by filtration and the filtrate was alkalified by adding 1 M sodium hydroxide aqueous solution. After extraction with ethyl acetate, the organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The residue concentrated under a reduced pressure was recrystallized from a mixed solvent of ethyl acetate and n-hexane, thereby obtaining 44 mg of 2-(4-aminomethylanilino)-4-(3-methylanilino)pyrimidine-5-carboxamide (light yellow crystals).
