Procedure

Under a nitrogen atmosphere, 4-(2-methoxy-4-(methylamino)-5-nitrophenoxy)pyridin-2-amine (1 eq) and disopropylethylamine (4 eq) in methylene chloride was brought to 0° C. Acetyl chloride (1.1 eq) was added dropwise and mixture stirred for 5 minutes. Reaction brought to room temperature and water added. Organic layer washed with brine, dried over sodium sulfate and concentrated to yield N-(4-(2-methoxy-4-(methylamino)-5-nitrophenoxy)pyridin-2-yl)acetamide. HPLC=3.21 min; MS: MH+=333.
