YieldReaction ConditionsOperation in experiment
28.5% With acetic acid; sodium nitrite In water at 0 - 20℃; Intermediate 4: 5-Bromo-7-methoxy-1H-indazole To a solution of 4-bromo-2-methoxy-6-methylaniline (5 g, 23.1 mmol, 1.0 eq) in glacial acetic acid (50 mL) at 0 °C was slowly added aqueous sodium nitrite solution (3.19 g, 46.3 mmol, 2.0 eq). The resulting reaction mixture was stirred at room temperature for overnight. The reaction was quenched with water (100 mL). The resulting mixture was extracted with ethyl acetate (3 x 100 mL). The organic layers were combined, dried over anhydrous sodium sulfate, filtered, and concentrated. The residue was purified by silica gel chromatography (0-50 % ethyl acetate / petroleum ether) to afford the 5-bromo-7- methoxy-1H-indazole as a red solid (1.5 g, 28.5 % yield)
With acetic acid; sodium nitrite In water at 15℃; for 14h; 4 To a solution of 4-bromo-2-methoxy-6-methylaniline (8.00 g, 37.0 mmol) in AcOH (80 mL) and water (16 mL) was added sodium nitrite (3.83 g, 55.5 mmol) and the reaction stirred at 15 °C for 14 h. The mixture was concentrated in vacuo, the residue was neutralised using saturated aq. NaHCO3 (100 mL x 3) and extracted with EtOAc (250 mL x 3). The combined organic layers were washed with brine (80 mL x 2), dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel using a Combiflash system, eluting with PE/EtOAc (75/25) to afford 5-bromo-7-methoxy- 1H-indazole (1.70 g, 17% yield) as a brown solid. 1HNMR (400MHz, DMSO-d6) d: 3.97 (s, 3H), 6.94 (s, 1H), 7.54 (s, 1H), 8.00 (s, 1H), 13.50 (s, 1H).

YieldReaction ConditionsOperation in experiment
74% With caesium carbonate; In N,N-dimethyl-formamide; at 80℃; for 1h;Microwave irradiation; To a solution of 5-bromo-7-methoxy-1H-indazole (1.00 g, 4.40 mmol) in N,N- dimethylformamide (16 mL) was added 4-bromo-1, 1,1 -trifluoro-butane (0.865 mL, 7.05 mmol) followed by Cs2CO3 (2.55 g, 13.2 mmol). The reaction was heated under microwave irradiation at 80C for 1 hour. The reaction mixture was poured into water and diluted with EtOAc. The phases were separated and the aqueous was extracted into EtOAc (x2). The combined organic extracts were washed with brine, dried over MgSO4 and concentrated in vacuo. The crude material was purified by column chromatography on silica gel using a gradient of 0- 70% EtOAc/cyclohexane to give the desired product (1.10 g, 74%) as a yellow solid.
