Procedure
To a stirred mixture of (S)—N-(1-(8-chloro-1-vinylisoquinolin-3-yl)ethyl)-9-(4-methoxybenzyl)-9H-purin-6-amine 2 (3.6 g, 7.6 mmol, 1 eq) in a mixture of 1,4-dioxane (40 mL) and H2O (40 mL) at RT, osmium tetraoxide (5 mg) was added and the resulting mixture was stirred at RT for 30 min. To this mixture, sodium periodate (3.3 g, 15.2 mmol, 2 eq) was added and the resulting mixture was stirred at RT overnight. The reaction mixture was filtered through silica gel (10 g). The filtrate was extracted with DCM (3×60 mL), 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-carbaldehyde 5.
