5-(5-iodo-2-isopropyl-4-methoxy-phenoxy)-pyrimidine-2,4-diamine (3.6 g, 9 mmol) and 5.1 mL triethylamine was added to 120 mL dry THF, and the reaction mixture was cooled in an ice bath and stirred under nitrogen atmosphere. Chloroacetyl chloride (1.8 mL, 22.5 mmol) dissolved in 5 mL THF was added dropwise, and the reaction mixture was stirred for four hours, during which time the reaction mixture was allowed to slowly warm to room temperature. The reaction mixture was concentrated under reduced pressure, and the residue was partitioned between water and methylene chloride. The combined organic layers were washed with brine, dried (Na2SO4), filtered and concentrated under reduced pressure. The resulting oil was purified by flash chromatography 0%-20% “Magic Base”/methylene chloride) to give 2.65 g of N-[4-amino-5-(5-iodo-2-isopropyl-4-methoxy-phenoxy)-pyrimidin-2-yl]-2-chloro-acetamide as the major fraction.
