Reaction Steps

A mixture of methyl [4-chloro-6-(dimethylamino)-2-(4-nitrobenzyl)pyrimidin-5-yl]acetate (7.75 g, 21.25 mmol), dimethylammonium chloride (5.20 g, 63.74 mmol), and N,N-diisopropylethylamine (10.98 g, 84.98 mmol) in DMPU (50 mL) was heated at 150° C. in a sealed tube for 15 hours. After cooling to room temperature, the dark mixture was poured into water and extracted with ethyl acetate. The combined extracts were washed sequentially with water and brine, dried over anhydrous sodium sulfate, filtered, and concentrated to yield the crude product as a dark oil. Chromatographic purification of this crude product over silica gel eluting with 25% ethyl acetate in n-hexane containing 0.1% triethylamine gave methyl [4,6-bis(dimethylamino)-2-(4-nitro-benzyl)pyrimidin-5-yl]acetate (5.44 g, 69%) as a red colored oil.
