0.8 g of 3-aminopropyl methacrylamide hydrochloride was dissolved in a methanol solvent and 1.5 g of butyric anhydride and 0.9 g of triethylamine (TEA) were added thereto. The resultant mixture was stirred under ice-cooling for 4 hours. After the completion of the reaction, the solvent was distilled off with an evaporator and the precipitate was filtered off. The filtrate was recovered and introduced into a silica column. Thus, the eluate fraction containing the target product was taken up and subjected to recrystallization to thereby purify the target butyrylamide, N-3-propyl methacrylamide (yield: 92%).
