Sources of common compounds: trans-3-(3-Pyridyl)acrylic acid

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 19337-97-4, trans-3-(3-Pyridyl)acrylic acid.

Application of 19337-97-4, 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. 19337-97-4, name is trans-3-(3-Pyridyl)acrylic acid, molecular formula is C8H7NO2, 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.

To a solution of (E)-3-(pyridin-3-yl)acrylic acid (0.40 g, 2.68 mmol, 1 eq) in DMF dry (4.0 mL), ammonium chloride (0.85 g, 16.10 mmol, 6 eq), HOBt (0.52 g, 3.86 mmol, 1.44 eq), EDCI (0.74 g, 4.20 mmol, 1.44 eq) and N-methylmorpholine (0.43 mL, 3.90 mmol, 1.44 eq) were subsequently added. The reaction was stirred at room temperature, under nitrogen for 3 h. After adding water, the reaction was filtered off through a neutral alumine oxide pad, washing with EtOAc/MeOH 9:1 (3 * 10 mL). The filtrate was evaporated and the residue was purified by column chromatography, using EtOAc/MeOH 9:1 as eluant to give 5 as white solid after crystallization with EtOAc (0.34 g, 85%).
