Procedure

A mixture of (S)-8-chloro-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carbaldehyde 5 (270 mg, 0.57 mmol, 1.0 eq) and hydroxylamine hydrochloride (495 mg, 7.1 mmol, 13 eq) in pyridine (4 mL) and MeOH (20 mL) was stirred at RT overnight. The reaction mixture was poured into water (50 mL) and extracted with DCM (3×30 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-3-(1-((9-(4-methoxybenzyl)-9H-purin-6-yl)amino)ethyl)isoquinoline-1-carbaldehyde oxime (240).
