37% | With sodium hydroxide; In water; at 40℃; for 0.25h; | Dimethylsulfate (2.7 mL, 0.058 mmol) was added carefully to 2-nitrobenzene-1,3-diol (2.5 g, 0.232 mmol) and the mixture was stirred vigorously while 10% NaOH solution (21 mL) was added and the temperature was kept below 40 C. After about 15 min, the mixture was cooled and then filtered. The filtrate was collected and acidified with 10% HCl, and extracted with ether (3×25 mL). The organic layer was dried (MgSO4), filtered, and concentrated under vacuum. Chromatography (10-30% EtOAc/hexanes) provided 9A10 (1 g, 37%). |

96% | With iodine; sodium hydrogencarbonate; at 0 - 20℃; for 1.0h; | Step 2: 6-Iodo-<strong>[3114-61-2]3-methoxy-2-nitrophenol</strong> A mixture of 1.36 g (8 mmol) of the product of Step 1 and 0.68 g (8 mmol) of sodium bicarbonate was sonicated at room temperature until it become homogenous. The resulting mixture was cooled to O0C and 2.04 g (8 mmol) of iodine was added. After stirring for 1 h at room temperature the precipitate formed was filtered off, dried and recrystallized from ethyl ether to give 2.28 g (96% yield of pure title compound as an orange crystals; 1H NMR (CDCl3) 3.92 (s, 3H, OMe); 6.41 (d, IH, CH J = 9Hz); 7.82 (d, IH5 J=9Hz); 10.37 (s, IH5 OH). |
