실험 절차

3′-Nitroacetophenone (2.00 g) was suspended in methyl t-butyl ether (12.1 ml), and sulfuryl chloride (4.90 g) was dropwise added thereto at 20° C. over 15 minutes. After stirring for 2 hours, precipitated solids were filtered and washed with methyl t-butyl ether. Drying under reduced pressure yielded the desired 2-chloro-3′-nitroacetophenone (1.62 g; 67.0%).
