Reaction Steps

To a cooled and stirred solution of 3-{4-[4-(4-chloro-phenyl)-6-methyl-pyrimidin-2-yl]-pyridin-2-yl}-benzenesulfonic acid tert-butylamide (0.47 g) in dichloromethane (6 mL) was added TFA (6 mL) and the reaction mixture was allowed to stir at room temperature for 15 h. The mixture was evaporated to dryness and saturated NaHCO3 solution (5 mL), diethyl ether and heptane were added. The mixture was stirred at room temperature for 1 h, the precipitate was collected by filtration, washed with water and heptane and dried to yield the title compound as a white solid (0.2, 46%). MS (ISP) 437.1 [(M+H)+]; mp 224° C.
