Reaction Steps

A mixture of (S)-8-chloro-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carbonitrile 29 (600 mg, 1.28 mmol, 1.0 eq), hydroxylamine hydrochloride (269 mg, 3.84 mmol, 3 eq) and NaOH (154 mg, 3.84 mmol, 3 eq) in EtOH (15 mL) was stirred at reflux 4 h. The mixture was cooled to RT, poured into water (100 mL) and then extracted with DCM (3×100 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 (1-10% MeOH-DCM) to afford the product (S,Z)-8-chloro-N′-hydroxy-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carboximidamide 30.
