389621-77-6, 2-(Tetrahydro-2H-pyran-4-yl)ethanamine hydrochloride is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

2-Bromo-N-(3,5-dibromopyrazin-2-yl)acetamide (3.30 g, 8.83 mmol) and 2-(tetrahydro-2H-pyran-4-yl)ethanamine hydrochloride (1.46, 8.83 mmol) and diisopropyl ethylamine (6.67 mL, 35.3 mmol) were combined and heated at 85 C. Upon complete consumption of starting material (by TLC), the reaction solution was condensed and purified using silica gel column chromatography (0-100% ethyl acetate in hexanes) to afford the title compound (1.53 g, 4.48 mmol, 50% yield).

389621-77-6, The synthetic route of 389621-77-6 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.389621-77-6,2-(Tetrahydro-2H-pyran-4-yl)ethanamine hydrochloride,as a common compound, the synthetic route is as follows.,389621-77-6

2-Bromo-N-(3,5-dibromopyrazin-2- yl)acetamide (3.30 g, 8.83 mmol) and 2-(tetrahydro-2H-pyran-4-yl)ethanamine hydrochloride (1.46, 8.83 mmol) and diisopropyl ethylamine (6.67 mL, 35.3 mmol) were combined and heated at 85 0C. Upon complete consumption of starting material (by TLC), the reaction solution was condensed and purified via Biotage chromatography (0-100 % ethyl acetate in hexanes) to afford the title compound (1.53 g, 4.48 mmol, 50 % yield). MS (ESI) m/z 341.4 [M]+, 343.1 [M+2]+.

As the paragraph descriping shows that 389621-77-6 is playing an increasingly important role.

389621-77-6, 2-(Tetrahydro-2H-pyran-4-yl)ethanamine hydrochloride is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

DIPEA (7.99 mL, 45.8 mmol) was added to a suspension of 2-(tetrahydro-2H-pyran-4- [ 5 yl)ethanamine hydrochloride (3.63 g, 21.89 mmol) in THF (30 mL, 366 mmol) and stirred for 15 min. A solution of 4-(4-fluoro-3-nitrophenyl)-3,5-dimethylisoxazole (4.7 g, 19.90 mmol) in THF (40 mL, 488 mmol) was added to the suspension and stirred at RT for a further 2h. DMF (10 mL, 129 mmol) was added and the reaction stirred at RT for a further 2h. The reaction was heated at 50C for 20h and then at 70C for a further 10 20h. The solvent volume was reduced by evaporation in vacuo and the residue diluted with EtOAc (200 mL). The solution was washed with water (3 x 50mL) and brine (30 mL), dried (MgS04), filtered and evaporated in vacuo. The residual solid was purified by chromatography on the Companion (220 g column, 0-30% EtOAc in (2: 1 DCM/isohexane), loaded in DCM) to give 4-(3,5-dimethylisoxazol-4-yl)-2-nitro-N-(2- 15 (tetrahydro-2H-pyran-4-yl)ethyl)aniline (5.6 g, 80%) as a orange solid; m/z 346 (M+H)+ (ES+).
