실험 절차

A solution of 2-chloro-3-nitrobenzoic acid (20.16 g, 100.0 mM), iodomethane (15.6 g, 110 mM), and potassium carbonate (15.0 g, 108.5 mM) in 100 mL DMF was stirred at room temperature for 48 hours. The mixture was poured into 1.5 liters of H2O. The resultant precipitate was collected by 20.0 g (93%) of methyl 2-chloro-3-nitrobenzoate as a white solid. 1H NMR (CDCl3) δ8.42 (dd, 1H, J=1 and 8 Hz), 8.18 (dd, 1H, J=1 and 8 Hz), 7.43 (t, 1H, J=8 Hz), and 3.9 (s, 3H). IR (KBr, cm−1) 1743, 1719, 1595, 1540, 1532, 1433, 1357, 1300, and 730. MS (FD) m/e 215, 216.
