Electric Literature of 13958-93-5, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 13958-93-5 as follows.
Preparation of 3,5-Dichloro-N-[4-(2-hydroxy-ethyl)-benzyl]-isonicotinamide: Using the EDCI coupling general procedure F: Reaction of 2-(4-Aminomethyl-phenyl)-ethanol (306 mg, 2.03 mmol), 3,5-dichloroisonicotinic acid (385 mg, 2.03 mmol), 1-hydroxybenzotriazole (301 mg, 2.22 mmol), 4-methyl morpholine (0.50 mL, 4.45 mmol), and EDCI (426 mg, 2.22 mmol) in anhydrous DMF (5 mL) overnight at room temperature and overnight at 40 C. followed by column chromatography on silica gel (2:2:96 MeOH-NH4OH-CH2Cl2) gave the title compound (291 mg, 44%) as a white foam.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,13958-93-5, its application will become more common.
