<Synthesis of Methacryloyloxyethyl Acrylamide (A1-3)>
N-(2-hydroxyethyl)acrylamide (available from Tokyo Chemical Industry Co., Ltd.) (13.0 g, 113 mmol) was added in dehydrated dichloromethane (70 mL). After a flask was internally purged with an argon gas, triethyl amine (17.2 g, 170 mmol) was added. After the resultant mixture was cooled to about −10 degrees C., methacrylic acid chloride (14.6 g, 140 mmol) was slowly dropped to adjust the temperature in the system to from −10 degrees C. through −5 degrees C., followed by stirring at room temperature for 2 hours. A precipitate was removed by filtration, the filtrate was washed with water, a saturated sodium bicarbonate aqueous solution, and a saturated sodium chloride aqueous solution, followed by drying with sodium sulfate and concentration at a reduced pressure, to obtain a brown oily matter.
The obtained oily matter was refined by column chromatography (WAKOGEL C300, 500 g), to obtain a colorless oily matter (13.0 g) (at a yield of about 66%).
In the manner described above, methacryloyloxyethyl acrylamide (A1-3) was synthesized.
