Reaction Steps

A solution of N-(5-bromo-4-(trifluoromethyl)thiazol-2-yl)-2-(2-tert-butylphenoxy)pyridin-3-amine (Example 323a, 1.3 g, 2.75 mmol) in dioxane (30 mL) was added tributyl(1-ethoxyvinyl)tin (1.1 mL, 3.3 mmol) was degassed and Pd(PPh3)4 (160 mg, 0.14 mmol) was added. The mixture was degassed and heated at 100° C. overnight. The mixture was concentrated on vacuum, dissolved in EtOAc and treated with saturated KF solution. The solid was removed by filtering through a pad of Celite®. The filtrate was extracted with EtOAc. The organic layers were combined, washed with bring, dried over magnesium sulfate and concentrated to give crude Example A154a (1.12 g) as a brown oil.
