Procedure
To a cooled (−78° C.) solution of 2,4-dichloro-6-methyl-5-nitropyrimidine (208 mg, 1.0 mmol, 1.0 eq. in 2 mL each of EtOH and THF) was added 2-methylimidazole (164 mg, 2.0 mmol, 2.0 eq.) in 2 mL of EtOH. The resulting mixture was stirred for 1 hour at −78° C., then for 2 hours at 0° C. Diethylamine (0.413 mL, 4.0 eq.) was added dropwise and the reaction was stirred overnight. The resulting mixture was diluted with dichloromethane, washed with 0.1N HCl, saturated NaCl, dried (MgSO4), and filtered. Solvent was removed by evaporation and the residue was purified by silica gel chromatography to provide 35 mg of the target compound k as an oil.
