実験手順

To a mixture of 0.62 g of 2-chloro-5-nitrobenzoic acid and 0.61 g of triethylamine in 5 ml of methylene chloride is added 0.42 g of isobutylchloroformate at 0° C. The mixture is warmed to room temperature for 30 minutes. A solution of 0.31 g of 5-(4-aminobenzoyl)-6,7-dihydro-5H-dibenz[b,d]azepine in 1 ml of methylene chloride is added followed by 10 mg of N,N-dimethylaminopyridine and 1.0 ml of toluene is added. The mixture is heated at 100° C. for 48 hours. The room temperature reaction mixture is diluted with 15 ml of ethyl acetate and washed with 1N HCl, 1N NaOH, brine and dried (Na2 SO4) and evaporated in vacuo to a residue. The residue is purified by column chromatography on silica gel by elution with 1:2 ethyl acetate-hexane to give 0.28 g of the desired product as a yellow solid. MS(CI):536(M+H).
