Electric Literature of 1314353-68-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1314353-68-8, name is 5-Cyclopropylpyridin-3-amine, molecular formula is C8H10N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

3-Amino-5-cyclopropylpyridine obtained in the above-described Step 1 (67 mg) and p-toluenesulfonic acid monohydrate (10 mg) were added to a solution of ethyl 5-chloro-3-(methylthio)-1,2,4-triazine-6-carboxylate (70 mg) in DMF (1 ml), and the reaction solution was stirred in a microwave reactor at 100C for 30 minutes. The reaction solution was diluted with ethyl acetate, and washed successively with an aqueous sodium bicarbonate solution, water, and a saturated saline solution. After drying over anhydrous sodium sulfate, the solvent was evaporated under vacuum. The resultant residue was purified by column chromatography on silica gel (developing solvent: hexane/ethyl acetate) to obtain ethyl 5-(5-cyclopropylpyridin-3-ylamino)-3-(methylthio)-1,2,4-triazine-6-carboxylate as a white solid.

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1314353-68-8, 5-Cyclopropylpyridin-3-amine.

Adding a certain compound to certain chemical reactions, such as: 1314353-68-8, 5-Cyclopropylpyridin-3-amine, 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, Quality Control of 5-Cyclopropylpyridin-3-amine, blongs to pyridine-derivatives compound. Quality Control of 5-Cyclopropylpyridin-3-amine

At 0 C, to a solution of 5-cyclopropylpyridin-3-amine (2.08 g, 15.49 minol) in tetrahydrofuran (30 mL) was added a solution of NaHMDS (6.84 g, 37.30 minol) in tetrahydrofuran (20 mL) dropwise over 10 min period. The resulting solution was stirred for 1 h at 0 C, and then was added by a solution of di-tert-butyl dicarbonate (4.85 g, 22.20 minol) in tetrahydrofuran (25 mL) dropwise. The resultingminxture was stirred for additional 2 h at room temperature. When the reaction was done, it was quenched by the addition of sat. NH4C1 solution (100 mL). The resultingminxture was extracted with ethyl acetate (100 mL x 3). The organic phases were combined, washed with brine and dried over Na2SO4. The solvent was removed under reduced pressure and the residue was purified by flash chromatography eluting with MeOH in EtOAc (0% to 80% gradient) to yield tert-butyl N-(5- cyclopropylpyridin-3-yl)carbamate as white solid (2.52 g, 69%). MS: m/z = 235.0 [M+Hj.
