Procedure

To a solution of (S)-2-amino-4-((1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carbonitrile (53) (495 mg, 1.19 mmol) in anhydrous 1,4-dioxane (20 mL), sulfuric acid/water (1:1, 7 mL) was added dropwise. The reaction mixture was stirred at 90° C. for 60 h. The mixture was allowed to cool to RT and basified with NaHCO3. The precipitate was collected by filtration and then dissolved in water. The resulting mixture was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo to afford the product 117, (S)-2-amino-4-((1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)amino)pyrimidine-5-carboxylic acid. The material was used directly in the next step.
