Potassium Carbonate → 2-Methoxy-1,3-dimethyl-5-nitrobenzene

関与物質

反応手順

2,6-Dimethyl-4-nitroaniline (15 g) Me2SO4 (22 g) and K2CO3 (23 g) were dissolved in 150 mL acetone and refluxed for 3 hours. The reaction mixture was filtered and concentrated. The organic residue was dissolved in warm hexane and let to crystallize out in the fridge. After filtration, 2-methoxy-1,3-dimethyl-5-nitrobenzene was collected as white solid (12 g). 1H-NMR (300 MHz, CDCl3): δ=7.95 (s, 2H), 3.80 (s, 3H), 2.38 (s, 6H) ppm. MS: m/z 182 (100, M+H)+
