Tetrahydrofuran → 4,6-Dimethyl-2-[(4-nitrobenzyl)sulfanyl]pyrimidine

Participants

Reaction Steps

To 4,6-dimethylpyrimidine-2-thiol (9.1 g) was added THF (70 ml), and to this solution was added triethylamine (21.5 ml) and then, 4-nitrobenzyl bromide (10 g), and the mixture was stirred for 5 hours at 50° C. After cooling to room temperature, the mixture was added to water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure and the obtained residue was washed with hexane/ethyl acetate, to give 4,6-dimethyl-2-[(4-nitrobenzyl)sulfanyl]pyrimidine (7.2 g).
