[0056] Synthetic Example 1. The preparation of intermediate M1, its synthetic route is as follows:
[0057]
[0058] The specific operation steps are:
[0059] 1,5-diaminonaphthalene (20mmol, 3.16g) and methyl acrylate (60mmol, 5.16g), AlCl 3 (60mmol, 7.92g) were mixed and dissolved in 50ml xylene, slowly heated to reflux and stirred, and the end point of the reaction was monitored by thin-layer chromatography (TLC), and the reaction was completed in 5 hours. Quenched with water, extracted with toluene, the extract was concentrated, passed through a silica gel column, the eluent was petroleum ether:ethyl acetate=5:1, and the eluent was concentrated to obtain intermediate M1-A (4.3g, yield 65 wt. %).
[0060] Intermediate M1-A (12mmol, 4.0g) was dissolved in 40mL of propylene glycol phenyl ether acetate (PPA), and the temperature was raised to reflux and stirred for reaction. The end point of the reaction was monitored by TLC, and the reaction was completed in 2 hours. Th...
