Related Products of 5683-33-0, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.5683-33-0, name is 2-(Dimethylamino)pyridine, molecular formula is C7H10N2, molecular weight is 122.17, as common compound, the synthetic route is as follows.

To a solution of the (2R)-2-phenylpropylamine (1.2g, 8.87 mmol) in hexane (16.0 mL) was added triethylamine (2.47 mL, 17.74 mmol) and is dimethylaminopyridine (0.30 g, 2.47 mmol). Cooled reaction to 5 C., then added a solution of isopropylsulfonyl chloride (0.97 mL, 8.69 mmol) dissolved in methylene chloride (6.0 mL) over a period of 15.0 minutes. Stirred for 45.0 minutes, then stirred at room temperature for 120.0 minutes. Quenched reaction with 1N HCl (20.0 mL) and extracted organic with methylene chloride (25.0 mL). Dried organic layer with anhydrous magnesium sulfate, filtered and concentrated filtrate to provide the final title compound, ((2R)-2-phenylpropyl)[(methylethyl)sulfonyl]amine, (1.93 g, 90.1%) an oil; 1H nmr (CDCl3, 300 MHz) delta 1.25 (d, 3H, J=6.9 Hz), 1.29 (d, 3H, J=6.9 Hz), 1.30 (d, 3H, J=7.2 Hz), 2.98 (m, 1H), 3.05 (m, 1H), 3.22 (m, 1H), 3.36 (m, 1H), 3.89 (b, 1H), 7.23 (m, 2H), 7.34 (m, 2H).

The chemical industry reduces the impact on the environment during synthesis 5683-33-0, I believe this compound will play a more active role in future production and life.

With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.5683-33-0, name is 2-(Dimethylamino)pyridine, molecular formula is C7H10N2, molecular weight is 122.17, as common compound, the synthetic route is as follows.Recommanded Product: 5683-33-0

A solution of 5-tert-butyl-2-(2-hydroxyethoxy)-1-nitrobenzene (0.401 g, 1.68 mmol), di-tert-butyl dicarbonate (0.46 mL, 2.0 mmol) and dimethylaminopyridine (0.006 g, 0.05 mmol) in CH2Cl2 (15 mL) was stirred at room temp. for 30 min, at which time TLC indicated consumption of starting material. The resulting mixture was washed with water (20 mL), dried (MgSO4) and concentrated under reduced pressure. The residue was purified by column chromatography (3% MeOH/97% CH2Cl2) to give the desired product as a yellow oil (0.291 g, 51%): 1H-NMR (DMSO-d6) ? 1.25 (s, 9H), 1.38 (s, 9H), 4.31 (br s, 4H), 7.27 (d, J=9.2 Hz, 1H) 7.64 (dd, J=2.6, 8.8 Hz, 1H) 7.77 (d,J=2.6 Hz, 1H).
