Reaction Steps

To a solution of 2-(5-chloro-2-methyl-phenyl)-5-(2-methylamino-pyrimidin-4-yl)-1H-pyrrole-3-carbonitrile (1.15 g, 3.55 mmol) in TFA (15.0 mL) were sequentially added water (2.25 mL) and 98% sulfuric acid (4.5 mL) under efficient stirring. The mixture was allowed to stir for 8 h at 70° C. and then was diluted by drop wise addition of water (45 mL). The reaction mixture was made basic (pH 10-12) by adding 30% aqueous ammonia (15 mL) under stirring. The precipitated solid was collected by filtration, washed with water and finally dried in a vacuum oven at 50° C. affording the title compound as an off-white solid (1.07 g, 88%).
