Reaction Steps

To (6-{[2-amino-5-chloro-4-(trifluoromehyl)phenyl]amino}-3-pyridinyl}ethanol (787 mg, 2.37 mmol, from step 5) was added propionic acid and propionic anhydride and stirred at 120° C. for 15 h. The mixture was quenched with NaOH and extracted with dichloromethane (3×30 ml). The organic layer was washed with brine, dried (MgSO4) and concentrated to give 5.26 g of title compound as orange oil.
