Chloroacetyl chloride → N-(4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-yl)-2-chloroacetamide

Participants

Reaction Steps

A solution of 4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-amine (1 eq) and triethylamine (2 eq) in tetrahydrofuran was treated with 2-chloroacetyl chloride and stirred for 15 minutes at room temperature. The reaction mixture was then concentrated and partitioned between ethyl acetate and water. The organic layer was separated and washed with brine, dried over sodium sulfate and concentrated in vacuum to give crude product. Purification on silica gel with 2% methanol in methylene chloride gave N-(4-(4-(methylamino)-3-nitrophenoxy)pyridin-2-yl)-2-chloroacetamide as a bright orange solid. HPLC=3.82 min; MS: MH+=337.
