反応手順

As presented in the following reaction formula, a solution of benzoyl chloride (PhCOCl; 6.7 g, 0.043 mol) in dichloromethane (DCM; 20 mL) was added at 0° C. to a mixture of 3-methyl-6-nitro-2,3-dihydro-1-H-inden-1-one (7 g, 0.043 mol) and triethylamine (9.6 g, 0.095 mol) in dichloromethane (DCM; 100 mL), and the reaction mixture was stirred for 2 hours. After the completion of reaction, the mixture was washed with water (50 mL), saturated sodium hydrogen carbonate (50 mL) and saturated brine (50 mL) and then concentrated to give a crude product. The crude product was purified by silica gel (50 g) column chromatography (product of Merck Co., Ltd.) using an eluent of pentane (PE):ethyl acetate (10:1 (by volume)) to give the desired product N-(1-methyl-3-oxo-indan-5-yl)benzamide (10 g, yield: 87%) as a yellow solid.
