実験手順
A mixture of 1-(4-bromopyridin-2-yl)hydrazine (1.00 g, 5.3 mmol) and 2-chlorobenzoyl chloride (8.00 ml, 63 mmol, Aldrich) was heated to 115° C. for 3 h. The mixture was diluted with MeOH and concentrated over SiO2. The residue was purified using column chromatography (MeOH/CH2Cl2=0-10%) yielding the title compound as a tan solid. MS (ESI, pos. ion) m/z: 264.0 (M+1).
