PROCEDURE

实验过程

5-Amino-3-(N-t-butoxycarbonylpiperid-4-yl)-1H-indole and 2-chloro-3-nitropyridine were used. Triethylamine was the base, dioxane was the reaction solvent, the reaction was heated at reflux (101° C.) for 5 hours, and the chromatographic solvent system was ethyl acetate [30-40%] in hexanes to afford the title compound (70%) as a dark red foam: 1H NMR (CDCl3) δ155.8, 155.0, 151.6, 135.5, 134.6, 129.4, 126.9, 121.3, 120.8, 119.8, 114.8, 113.1, 111.5, 79.4, 44.5, 33.6, 32.8, 28.5. Anal. calcd. for C23H27N5O4.1/4 C4H8O2 [ethyl acetate]: C, 62.73; H, 6.36; N, 15.24. Found: C, 62.51; H, 6.08; N, 15.21.
