Reaction Steps
Subsequently, the aniline compound of formula (II) is subjected to a reaction with an acryloyl chloride substituted with A and B, in an organic solvent (e.g., methylene chloride or tetrohydrofuran) or a mixed solvent such as 50% aqueous tetrohydrofuran in the presence of an inorganic base (e.g., sodium bicarbonate) or organic base (e.g., triethylamine or diisopropylethylamine) at a low temperature ranging from −10° C. to 10° C.; or with acrylic acid substituted with A and B, in pyridine using a coupling agent (e.g., 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDCI) or 2-(1H-7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyl uronium hexafluoro phosphate methaneaminium (HATU)), to obtain the inventive compound of formula (I) having an acrylamide group.
