実験手順
In a 1 liter 3-necked flask were combined 400 ml dry THF and 40 ml distilled n-butylamine (0.405 mol). After cooling to 5° C. in an ice bath, 20 ml (0.205 mol) methacryloyl chloride was added slowly so as to keep the temperature below 10° C. The precipitate was removed by filtration, and the filtrate concentrated on a rotary evaporator. 1 g DNPD was added and the oil distilled at 76°-78° C. and 20 m torr. Yield 24.3 g (84%).
