[0029]
[0030] The preparation of 7-benzo (c) acridine benzamide thiourea ④, the specific steps are as follows:
[0031] The following raw materials are calculated in parts by weight:
[0032] 1) In a three-necked flask, add 12 parts of o-bromobenzoic acid, 8 parts of naphthylamine, 13 parts of potassium carbonate and 0.9 parts of copper powder, add 65 parts of n-pentanol as a solvent, react at 100°C for 1 hour, and remove under reduced pressure After n-pentanol, add 400 parts of water and react at 60℃ for 20 minutes. After filtering, wash the filter cake with water, collect the washed water and combine the filtrate, acidify with concentrated hydrochloric acid to pH 2, and precipitate a large amount of purple black precipitate , Suction filtration, the obtained black solid is recrystallized with acetone, a...
