Reaction Steps

Add iron powder (6.0 g) to a solution of 4,6 dichloro-2-methyl-5-nitro-pyrimidine (6.50 g, 31 mmol) in acetic acid (11 mL) and MeOH (50 mL). Heat the resulting mixture at 65° C. for 1 h. After cooling, to ambient temperature, filter the mixture through a pad of celite, and evaporate the filtrate to dryness under reduced pressure. Treat the residue with 1N aq NaOH, and extract with EtOAc. Wash the EtOAc extract with water and saturated aq NaCl, dry over Na2SO4, filter, and concentrate in vacuo to obtain the title compound as a solid.
