1.02 g | With iodine; potassium hydroxide In N,N-dimethyl-formamide at 1 - 40℃; for 1h; | 48.1 (1) Synthesis of 6-bromo-3-iodo-1H-indazole [36-1] (hereinafter referred to as a compound [36-1]) General procedure: (1) Synthesis of 6-bromo-3-iodo-1H-indazole [36-1] (hereinafter referred to as a compound [36-1]) To a solution of 6-bromo-1H-indazole (1.11 g) in N,N-dimethylformamide (10 mL) were added iodine (2.17 g) and potassium hydroxide (1.14 g), and the mixture was stirred at room temperature for 1 hour. The reaction mixture was quenched with water, and extracted with chloroform. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the titled compound (1.45 g) as a yellow solid. 1H-NMR (400 MHz, CDCl3) δ: 11.22 (1H, s), 7.71 (1H, s), 7.39-7.31 (2H, m). |

Step 2. 6-Bromo-3-iodo-1-trityl-1H-pyrazolo[4,3-b]pyridine To a suspension of NaH (1.63 g, 40.8 mmol) in DMF (100 ml) at 0° C. was added a solution of 6-bromo-3-iodo-1H-pyrazolo[4,3-b]pyridine (12.0 g, 37.0 mmol) in 20 ml of DMF dropwise. After the addition was complete, the reaction mixture was warmed to r.t and stirred at that temperature for 30 min. The mixture was then cooled back to 0° C. and treated with a solution of (chloromethanetriyl)tribenzene (11.4 g, 40.8 mmol) in 20 ml of DMF. The reaction mixture was stirred at r.t for 2 h. Water was then added and the product was extracted with DCM. The organic phase was concentrated in vacuo. The resultant solid was collected by filtration and air-dried.
