[0069] (1-ethyl-2-oxo-N-(2-oxo-2-(pyrrolidin-1-yl)ethyl)-1,2-dihydrobenzo[cd]indole-6-sulfonamide)(E1)
[0070]
[0071] Step 1. 1,3-Dioxo-2,3-dihydro-1H-phenalen-2-yl 4-methylbenzenesulfonate
[0072] (1,3-dioxo-2,3-dihydro-1H-phenalen-2-yl 4-methylbenzenesulfonate)
[0073]
[0074] Add 1,8-naphthalic anhydride (1-1) (11.9 g, 0.06 mol), hydroxylamine hydrochloride (4.18 g, 0.06 mol) and pyridine (70 mL) into a round bottom flask, and heat to reflux for 1 hour. After cooling to 80°C, 4-toluenesulfonyl chloride (22.88 g, 0.12 mol) was quickly added, and the temperature was raised to reflux for 1.5 hours. After cooling to room temperature, the mixture was poured into 200 g of ice water, and a yellow precipitate precipitated out after stirring. Stand still, filter with suction, wash with water three times, stir and wash with saturated sodium bicarbonate sol...
