반응 단계
According to the procedure of B. Agai, et al., Tetrahedron, 32, 839, (1976), a solution of 1-chloro-2-nitrobenzene (50.0 g, 0.317 mol) and 2-aminoethanol (116.3 g, 1.904 mol) in nBuOH (400 mL) was heated under reflux for 6 hours. The mixture was concentrated, taken up in H2O, and extracted with ether. The organic phase was washed with brine, dried, and concentrated to give 43.1 g (75%) of an orange solid m.p. 78° C.
