| Reactant | (4-Aminobut-1-yn-1-yl)trimethylsilane | HCID 19703099 | — |
| Product | 4-chloro-2-(4-trimethylsilanyl-but-3-ynyl)-2H-indazole | HCID 66597993 | 43% |
Reaction Steps
The title compound was prepared in accordance with the general method of Example 149(A), from 2-chloro-6-nitro-benzaldehyde (210 mg, 1.13 mmol) and 4-trimethylsilanyl-but-3-ynylamine (210 mg, 1.50 mmol). The crude product was purified by flash chromatography (cyclohexane/AcOEt 92.5:7.5) to yield 4-chloro-2-(4-trimethylsilanyl-but-3-ynyl)-2H-indazole (134 mg, 0.48 mmol, 43%) as a yellow oil.
