实验步骤: (4-Bromo-but-1-ynyl)-trimethyl-silane (294 mg, 1.43 mmol) was added to a solution of 5-fluoro-1H-benzo[d][1,2,3]triazole (187 mg, 1.36 mmol) in a solution of NaOH (2N, 955 μL). The reaction mixture was heated at 100° C. for 14 hours, then it was cooled down and was extracted with DCM. The organic phase was washed with water, brine, dried over MgSO4, filtered and evaporated to yield 355 mg (1.36 mmol) 5-fluoro-2-(4-trimethylsilanyl-but-3-ynyl)-2H-benzo[d][1,2,3]triazole including the two others isomers. it was cooled down was extracted with DCM The organic phase was washed with water, brine dried over MgSO4 filtered evaporated

反应条件: temp:150.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A suspension of (4-bromo-but-1-ynyl)-trimethyl-silane (374 mg, 1.83 mmol), indazole (200 mg, 1.69 mmol) and K2CO3 (459 mg, 3.32 mmol) in acetone (2 mL) was heated at 150° C. for 900 s in a microwave. After the addition of water, acetone was evaporated. The aqueous phase was extracted with DCM. The organic phase was washed with brine, dried over MgSO4, filtered and evaporated to yield 250 mg (1.03 mmol, 62%) of 2-(4-trimethylsilanyl-but-3-ynyl)-2H-indazole and 1-(4 trimethylsilanyl-but-3-ynyl)-1H-indazole. was evaporated The aqueous phase was extracted with DCM The organic phase was washed with brine dried over MgSO4 filtered evaporated

实验步骤: 4-Trimethylsilyl-3-butyne-1-ol (14.2 g, 0.1 mol) and 0.2 ml of pyridine were dissolved in 50 ml of diethyl ether under a nitrogen atmosphere. Phosphorus tribromide (3.8 ml, 0.04 mol) was slowly added and the mixture was heated under reflux for 2 hours. Isolation of the product by conventional means yielded 9.6 g of 4-bromo-1-trimethylsilyl-1-butyne as a clear liquid, bp 35°-38° C. at 1 mm Hg. the mixture was heated under reflux for 2 hours
