Application of 131747-62-1, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 131747-62-1, name is 3-(Trifluoromethyl)pyridine-2-carboxaldehyde. A new synthetic method of this compound is introduced below.

To a solution of 165 (100 mg, 0.518 mmol) in toluene 15 ml was added 66 (99.7 mg, 0569 mmol). PTSA (196.8 mg 1.03 mmol) was added to the reaction mass, which was then stirred at 120 C. for 12 h. The reaction mass was diluted with ethyl acetate and washed with water (3×25 ml.). The organic layer was dried over sodium sulphate and concentrated to get the crude, which was used in the next step with out further purification.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,131747-62-1, its application will become more common.

Synthetic Route of 131747-62-1, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 131747-62-1, name is 3-(Trifluoromethyl)pyridine-2-carboxaldehyde. This compound has unique chemical properties. The synthetic route is as follows.

Sodium triacetoxyborohydride (40 mg, 0.19 mmol) was added to a solution of (3-((1- amino-2,3-dihydro-1 H-inden-5-yl)methyl)-5-(trifluoromethyl)phenyl)methanol (30 mg, 0.093) and 3-trifluoromethyl-2-formylpyridine (15 mg, 0.086 mmol) in DCM (1 ml_). The reaction was stirred at rt for 24 h before aq. sat. NaHCO3 (2 ml.) was added to the mixture was filtered over a phase separator. The organic filtrate was evaporated to dryness in a Genevac. The crude material was purified by prep. LCMS to afford the title compound (18.9 mg, 42.1 %). MS (ESI) : m/z [M + H]+ 481.2

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 131747-62-1, 3-(Trifluoromethyl)pyridine-2-carboxaldehyde.

Intermediate 1: (S)-(4-(Trifluoromethyl)phenyl)(3-(trifluoromethyl)pyridin- 2-yl)methanamine hydrochlorideStep 1. (S^)-2-Methyl-N-((3-(trifluoromethyl)pyridin-2-yl)methylene)- propane-2-sulfinamideTo a solution of 3-(trifluoromethyl)picolinaldehyde (Frontier Scientific, 9.80 g, 56.0 mmol) and DCM (50 mL) was added (5)-2-methylpropane-2- sulfinamide (AK Scientific, 10.3 g, 85.0 mmol) and copper(II) sulfate (35.3 g, 221 mmol). After 1.5 h at rt, the reaction was filtered through a pad of Celite brand filter agent and rinsed with DCM. The filtrate was concentrated in vacuo to give a dark green oil. The oil thus obtained was loaded onto a silica gel column and eluted with 30% EtOAc in hexanes to give (S,E)-2-methyl-N-((3-(trifluoro- methyl)pyridin-2-yl)methylene)propane-2-sulfinamide, as a golden oil. 1H NMR (delta ppm, CDCI3, 300 MHz): 9.02 (d, J = 4.3 Hz, 1H), 8.70 (d, J = 1.3 Hz, 1H), 8.38 (d, J = 7.7 Hz, 1H), 7.79 (dd, J = 7.9 & 4.8 Hz, 1H), 1.18 (s, 9H).
