Reaction Steps

A mixture of 2-amino-N-methyl-benzenesulfonamide (2.93, 15.75 mmol), 2,4,5 trichloropyrimidine (2.9 g, 15.84 mmol) and K2CO3 (4.5 g, 32.6 mmol) in dry DMF (25 mL) was stirred at 45° C. for 15 h. The solvent was removed and the residue was taken in water and was extracted twice from ethylacetate. Combined organic was washed with water and brine. After drying solvent was removed. Upon triturating with ether and filtration gave the product 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzenesulfonamide 7 as a white solid (2.6 g, 50%); 1H NMR (400 MHz, CDCl3) δ9.61 (s, 1H), 8.6 (d=12.89 Hz, 1H), 8.53 (s, 1H), 8.27 (s, 1H), 7.68 (m, 1H), 7.27 (m, 1H0, 1.66 (br s, 1H0, 2.66 (s, 3H).
