Procedure
Among the (meth)acrylamide derivatives represented by the general formula (1), a compound (the above compound A-1) in which R1 is a hydrogen atom; R2 is an ethoxymethyl group; and R3 to R6 are a hydrogen atom can be synthesized, for example, by the following manner. In this manner, o-aminophenol is reacted with acryloyl chloride in N-methyl-2-pyrrolidone (NMP) in the presence of lithium chloride to obtain N-(2-hydroxyphenyl)acrylamide. N-(2-hydroxyphenyl)acrylamide is then reacted with chloromethyl ethyl ether in NMP in the presence of N,N-diisopropyl ethylamine to synthesize the above compound A-1.
