Embodiment

[0202] A) Synthesis Example

[0203] Synthetic Precursor V1:

[0204]

[0205] CAS number: 918163-16-3

[0206] Step 1: 2-Chloro-9,9-dimethyl-9,10-dihydroacridine

[0207] 30.3 g (116 mmol) of 2-[2-(4-chlorophenylamino)phenyl]propan-2-ol were dissolved in 700 ml of degassed toluene, a suspension of 93 g of polyphosphoric acid and 61.7 g of methanesulfonic acid was added, and The mixture was stirred at room temperature for 1 hour and heated at 50 °C for 1 hour. The batch was cooled, added to ice, and extracted three times with ethyl acetate. The combined organic phases were washed with saturated sodium chloride solution, dried over magnesium sulfate and evaporated. The crude product was filtered through silica gel using heptane / ethyl acetate (20:1) to afford 25.1 g (89%) of 2-chloro-9,9-dimethyl-9,10-dihydroacridine as pale yellow crystals.

[0208] Step 2: 10-Biphenyl-4-yl-2-chloro-9,9-dimethyl-9,10-dihydroacridine

[0209]

[0210] A degassed solution of 57.9 g (2...
