Reaction Steps

A solution of (S)-tert-butyl 1-(4-(4-(2-chloro-3-(propylsulfonamido)phenyl)-2-cyclopropyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-imidazol-5-yl)pyrimidin-2-ylamino)propan-2-ylcarbamate (116 mg, 0.14 mmol) in EtOH (2 mL) was treated with aqueous 6.0 N HCl solution (0.8 mL, 4.8 mmol) and the resulting reaction was heated to 60° C. for 30 minutes, then at room temperature for 40 minutes. The reaction was allowed to cool to room temperature and the volatiles were removed in vacuo. Further drying under high vacuum afforded (S)—N-(3-(5-(2-(2-aminopropylamino)pyrimidin-4-yl)-2-cyclopropyl-1H-imidazol-4-yl)-2-chlorophenyl)propane-1-sulfonamide (80 mg, 0.15 mmol) as the HCl salt (4A-2) which was used without further purification: LCMS (m/z) 490.2 (MH+), tR=0.48 minute.
