Reaction Steps

A solution of 2.7 g (0.01 mol) of 2-amino-4-chloro-6-{[(2,2-dichloro-cyclopropyl)methyl]amino}pyrimidine in 300 ml of acetonitrile was added dropwise, while stirring, at room temperature over a period of 15 minutes to a solution of 0.9 gm (0.012 mol) of acetic acid-formic acid anhydride in 5 ml of acetonitrile. After stirring the mixture for about 30 hours at room temperature the solvent was distilled off in vacuo, and the residue was treated twice by dissolving it in about 30 ml of toluene and then distilling the toluene off again. The raw product was purified by column chromatography (150 gm silica gel; eluant: Diisopropyl ether/ethyl acetate 9:1), yielding the title compound as white crystals.
