Adding a certain compound to certain chemical reactions, such as: 1309788-50-8, name is 3-Iodo-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indazole, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 1309788-50-8, SDS of cas: 1309788-50-8
To a solution of 3-iodo-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indazole (41 g, 147 mmol), triethylamine (22 ml, 155 mmol) and 4-dimethylaminopyridine (824 mg, 7 mmol) in tetrahydrofuran (163 ml) was added dropwise a solution of di-tert-butyl dicarbonate (34 g, 155 mmol) in tetrahydrofuran (41 ml) at room temperature over 40 min, and the mixture was stirred for 30 min. Then, the reaction mixture was is concentrated under reduced pressure. The residue was slurry-washed in hexane (130 ml) at 60 C. and ice-cooled. The crystals were collected by filtration, washed with hexane, and dried under reduced pressure to give the title compound (53 g, yield 95%).1H-NMR (400 MHz, DMSO-d6) delta: 0.95 (s, 6H), 1.46 (t, 2H, J=6.38 Hz), 1.56 (s, 9H), 2.23 (t, 2H, J=6.26 Hz), 2.63 (s, 2H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Iodo-6,6-dimethyl-4,5,6,7-tetrahydro-1H-indazole, other downstream synthetic routes, hurry up and to see.
