Reaction Conditions

Reaction Steps

To a stirred solution of 2-methyl-N-(7H-purin-6-yl)propanamide (1.5 g, 24.36 mmol) in dimethylformamide (20 mL), sodium hydride (0.88 g, 36.55 mmol) was added portion wise in 10 minutes at 0° C. The above suspension was stirred for 10 minutes at 0° C. followed by addition of 2-(trimethylsilyl)ethoxymethyl chloride (4.87 g, 29.24 mmol) slowly at 0° C. under nitrogen atmosphere. The reaction was stirred at room temperature for 16 h. After completion of the reaction, the mixture was quenched with saturated aqueous solution of ammonium chloride and product was extracted with dichloromethane (2×50 mL). The organics were then separated, dried (magnesium sulfate) and concentrated to dryness under vacuum and the crude was purified by flash chromatography eluting with 2% methanol in dichloromethane. Concentration of the desired fractions afford 2-methyl-N-[7-(2-trimethylsilylethoxymethyl)purin-6-yl]propanamide (2) as white solid. Yield: 2 g, 24%.
