반응 단계
A mixture of i-propyl 4-chloro-3-nitrobenzoate (25.88 g, 0.11 mol), 3-bromoaniline (17.36 ml, 0.16 mol) and potassium carbonate (14.63 g, 0.11 mol) in N-methyl-2-pyrrolidone (25 ml) is heated to 150° C. for 3 days. After cooling the mixture is poured into diluted hydrochloric acid (300 ml, 1 M). The precipitate is filtered off, washed with water and dried (37.4 g). This crude product is washed with hot 2-propanol to afford pure 24 (26.25 g, 65%). Mp 162-165° C.
