To a suspension of (S)-tert-butyl (1-((3-(2-((4-cyanophenyl)amino)-4-(propylamino)pyrimidine-5-carboxamido)phenyl)amino)-1-oxopropan-2-yl)(methyl)carbamate (C8, 325 mg) in 1,4-dioxane (6 mL), a 4.0 mol/L solution of hydrochloric acid in 1,4-dioxane (6 mL) was added at room temperature, and the mixture was stirred at the same temperature for 4 hours. The solvent was evaporated under reduced pressure, ethyl acetate was added to the obtained residue, and the solid matter was taken by filtration to obtain (S)-2-((4-cyanophenyl)amino)-N-(3-(2 -(methylamino)propanamido)phenyl)-4-(propylamino)pyrimidine-5-carboxamide (E1) dihydrochloride (302 mg).
