Triethylamine → HCID 23153435, compound

Participants

Reaction Steps

N-(4-Fluorophenyl)-N′-[4-(2-aminopyridin-4-yloxy)-2-fluorophenyl]malonamide (20.2 mg) was dissolved in N,N-dimethylformamide (0.5 ml), and then triethylamine (0.042 ml) and propionyl chloride (0.013 ml) were added dropwise thereto under a nitrogen atmosphere at room temperature, followed by stirring overnight. To the reaction mixture was added a 1 N aqueous solution of sodium hydroxide (1.5 ml), followed by stirring and extracting with ethyl acetate. The organic layer was concentrated under a reduced pressure to give a residue, which was purified by silica gel column chromatography (FUJI Silysia NH, eluent; ethyl acetate). Fractions containing the target compound were concentrated to give a residue, which was then dried in vacuum to provide the titled compound (9.0 mg, 39%) as pale yellow powder.
