Reaction Steps

A mixture of 4-hydroxy-5-pyrimidinecarboxylic acid (0.88 g, 6.3 mmol) in 5 drops of DMF and 6 mL of thionyl chloride was heated at reflux for 3 hours. The mixture was concentrated and the residue was dissolved in methylene chloride. A mixture of the residue, dimethylamine hydrochloride (0.62 g, 7.6 mmol) and triethylamine (4.5 mL, 31.5 mmol) in 50 mL of methylene chloride was stirred at 0° C. for 0.5 hours. The mixture was poured into water and aqueous sodium bicarbonate. The mixture was extracted with methylene chloride (2×30 mL) and the extract was washed with brine, dried (Na2SO4) and concentrated by rotary evaporation to give 4-chloro-N,N-dimethyl-5-pyrimidinecarboxamide (0.66 g, 3.6 mmol) as an oil.
