Participants

Reaction Steps

A suspension of 551 mg (1.5 mmol) 5-[2-(2-fluoro-phenyl)-[1,8]naphthyridin-4-yl]-[2,6]naphthyridin-1-ylamine in 10 ml DMF was treated with 108 mg (4.50 mmol) sodium hydride and stirred for 1 h at room temperature. Then 356 mg (2.25 mmol) dimethylaminoacetyl chloride hydrochloride were added and the reaction mixture was stirred for 18 h at room temperature. The reaction mixture was partitioned between water and dichloromethane. The organic phase was dried over sodium sulfate and evaporated. The residue was chromatographed on a silica gel column with ethyl acetate/methanol as eluent yielding 2-dimethylamino-N-{5-[2-(2-fluoro-phenyl)-[1,8]naphthyridin-4-yl]-[2,6]naphthyridin-1-yl}-acetamide as brown amorphous solid; HPLC/MS (B) 1.64 min, [M+H] 453.
