[0129] Preparation Example 1: Synthesis of Compound 8
[0130]
[0131] Intermediate IM-A-1 (15.0g, 27.1mmol), 9,10-dihydro-9,9-dimethylacridine (6.2g, 29.8mmol), Pd 2 (dba) 3 (0.2g, 0.3mmol), tri-tert-butylphosphine (0.1g, 0.5mmol), sodium tert-butoxide (3.9g, 40.7mmol), and toluene (150mL) were added to a three-necked flask, and the temperature was raised to 110°C under nitrogen protection. Heat to reflux and stir for 5h, cool to room temperature, add toluene and extract the reaction solution, combine the organic phases, dry the organic layer with anhydrous magnesium sulfate, filter, and concentrate; use silica gel column chromatography (dichloromethane / n-heptane) to purify to obtain a solid Compound 8 (11.8 g, yield 64%). m S [M+H] + = 681.29.
[0132] The compounds shown in Table 1 below were synthesized in a similar manner to Preparation Example 1, except that starting material 1 was used instead of 9,10-dihydro-9,9-dimethylacridine.
