Participants

Reaction Steps

6-chloro-2-(4-methoxy-3-nitrobenzylsulfanyl)-9-methyl-9H-purine (100 mg, 0.273 mmol) was dissolved in dimethoxyethane (4 ml), then trans-propenylboronic acid (70 mg, 0.815 mmol) and tetrakis(triphenylphosphine)palladium (0) (30 mg, 0.025 mmol) were added. Then 106 mg (1.0 mmol) of sodium carbonate dissolved in water (2 ml) was added, and the mixture was heated to reflux for 2 hours. After cooling it, the insolubles were filtered off with Celite, the filtrate was distilled away under reduced pressure, ethyl acetate (20 ml) and water (20 ml) were added to the residue and extraction was performed. After washing with water, drying was carried out with anhydrous magnesium sulfate, the insolubles were filtered off, the filtrate was distilled away under reduced pressure, and the residue was subjected to silica gel column chromatography (ethyl acetate: methanol=50:1) to obtain 2-(4-methoxy-3-nitrobenzylsulfanyl)-9-methyl-6-(1-trans-propenyl)-9H-purine (87.5 mg, 86%).
