74370-93-7, 4-(tert-Butyl)thiazol-2-amine is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,74370-93-7

Into a Vial was added the 6-Chloro-pyridine-3-sulfonic thiazol-2-ylamide (35 mg, 0.00013 mol), Sodium tert-butoxide (36 mg, 0.00038 mol), 9,9-DIMETHYL-4,5-BIS(DIPHENYLPHOSPHINO)XANTHENE (8.8 mg, 0.000015 mol), Tris(dibenzylideneacetone)dipalladium(0) (4.6 mg, 0.0000051 mol), 2-AMINO-4-(4-CHLOROPHENYL)THIAZOLE and the de-gased anhydrous 1,4-Dioxane (1.7 mL, 0.022 mol). The reaction mixture was heated at 150 C. for 1 h in microwave. The reaction mixture was filtered through celite and the filtrate was concentrated to give the crude product that was purified on Gilson (semi-prep, reverse phase, Phenomenex 100¡Á21.2 mm 10 micron C18 column, 20 mL/min, Gradient 85% A to 100% B over 25 min. Solvent A: 7800 water/200 acetonitrile/8 TFA. Solvent B: 7200 acetonitrile/800 water/8 TFA). Fractions were checked by LC/MS and then dried on a lyophilizer to give the desired product as TFA salt (yellow powder).

The synthetic route of 74370-93-7 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.74370-93-7,4-(tert-Butyl)thiazol-2-amine,as a common compound, the synthetic route is as follows.

Synthesis of 2-bromo-4-tert-butylthiazole 85% strength phosphoric acid (50 ml) and 65% strength nitric acid (20 ml) were combined at 0 C. 3.12 g (20.0 mmol) of 4-tert-butylthiazol-2-ylamine were added to this solution and a solution of 1.38 g (20 mmol) of NaNO2 in water (10 ml) was subsequently added dropwise at 0 C. in the course of 30 min. The reaction solution was stirred at 0 C. 1 h and then added dropwise to a suspension of 20.0 g of NaBr and 5.8 g of CuBr in water (20 ml) cooled to 0 C. The mixture was stirred until evolution of gas could no longer be observed. Subsequently, the mixture was adjusted to a pH>10 using 50% strength aq. KOH solution and the product was separated off by steam distillation. The distillate was extracted with EE. The organic phase was dried over MgSO4, filtered, and concentrated in vacuo. 3.03 g (13.8 mmol, 69%) of 2-bromo-4-tert-butylthiazole were obtained as a residue.
