Procedure

A suspension of 5-chloro-2-methoxy-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)benzoic acid (144 mg, 50% pure material, 0.19 mmol), HATU (85 mg, 0.22 mmol), acetic hydrazide (16 mg, 0.22 mmol) and DIPEA (81 uL, 0.46 mmol) in dichloromethane (4 mL) was stirred at room temperature for 18 h. The mixture was diluted with dichloromethane (10 mL) and washed with saturated aqueous NaHCO3 solution (10 mL). A solid persisted in the aqueous layer; this was filtered, washed with water and then suspended in methanol. The solid was collected by filtration and dried in a vacuum oven to afford N′-acetoyl-5-chloro-2-methoxy-4-(4-(methylamino)-5-(trifluoromethyl)pyrimidin-2-ylamino)benzohydrazide as a white solid (68 mg, 85%). This was taken through to the next step without further purification.
