Procedure

To a solution of (S)-8-chloro-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carbaldehyde 5 (1.67 g, 3.53 mmol, 1 eq) in DMF (40 mL) at RT, oxone (6.5 g, 10.59 mmol, 3 eq) was slowly added and the resulting mixture was stirred at RT overnight. The reaction was complete based on TLC analysis. The reaction mixture was poured into water (50 mL) and neutralized with concentrated ammonium hydroxide to adjust the pH value to 7-8. The mixture was stirred at RT for 30 min and then extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (1-5% MeOH-DCM) to afford the product (S)-8-chloro-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carboxylic acid 10.
