Reaction Steps

To a flask containing methyl 3-amino-5-iodobenzoate (500 mg, 1.81 mmol) was added a solution of 2-chloro-4-(trifluoromethyl)pyrimidine (379 mg, 2.08 mmol) in dioxane (5.6 mL). Methanesulfonic acid (199 mg, 2.08 mmol) was added and the reaction was heated at 100° C. overnight. The reaction was cooled, diluted with ethyl acetate, washed with water, dried over magnesium sulfate, filtered and concentrated. Flash chromatography was used for purification to yield methyl 3-iodo-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}benzoate (538 mg, 1.27 mmol, 71% yield). MS ESI: [M+H]+ m/z 424.0.
