A mixture of 1,1,2-trimethyl-[1H]-benz[e]indole (10.0 g, 47.8 mmol) and 3-bromopropanoic acid (7.3 g, 47.8 mmol) in 1,2-dichlorobenzene (50 mL) was heated with stirring at 110° c. for 18 h. After the resulting mixture was cooled to room temperature, the precipitated was collected by filtration, triturated with DCM thoroughly, and dried under vacuum to afford 15.2 g of light brown powder (88%). ESI-MS: observed for [MH]+ 281.31.
