反応手順
2-Cyclopentoxyaniline (10.0 g, 0.057 mole), N-methylolpyrrolidone (9.75 g, 0.85 mole) and xylene (25 cc) were refluxed under azeotropic conditions with the removal of 1.5 cc of water. The xylene was removed by rotary evaporation and the product was crystallized from 100 cc of hexane to yield 8.0 g (51.6%) of product, m.p. 87°-87.5° C.
