Embodiment 1
[0153] [Example 1] Preparation of Compound A10
[0154]
[0155] 1-1. Preparation of Compound A3-1
[0156] The compound 9H-carbazole 16.7 g (0.100 mol) was placed in a 500-mL 3 neck round bottom flask, and 250 ml of N, N-dimethylformamide was diluted. In this diluent, there were 14.6 g of potassium tert-butoxide, and after 20 minutes of reflux, 2-bromo-4-chloro-1-fluorobenzene was placed in 23.0 g. After 10 hours of reaction, it was cooled to room temperature, and extracted with ethyl acetate and distilled water. The crude product obtained by concentrating concentrated under reduced pressure after drying extract was subjected to column separation, and Compound A3-123.2 g (yield was 65%).
[0157] 1-2. Preparation of Compound A3-2
[0158]The compound A3-1 19 g (0.053 mol), palladium acetate (II) 0.12 g, three (tert-butyl) phosphine, 0.22 g, carbonated 0.12 g, three (tert-butyl) phosphine 0.22 g, carbonated in 1000-mL 4 neck round bottom flask Potassium 14.7 g and 380 ml of dime...
Embodiment 2
[0163] [Example 2] Preparation of Compound A9
[0164]
[0165] 2-1. Preparation of Compound A9-1
[0166] Trio (sillazyl acetone) palladium (0) 0.25 g, tricyclic hexylphosphine 0.30 g, and 1,4-dioxane 360 mL were placed in a 1000-mL 4 neck round bottom flask. At room temperature, the mixture was stirred for 30 minutes, and Compound A3-2 18.3 g (0.066 mol) prepared in Examples 1-2 was put into Examples 1-2, bis (which alcohol) di boron 18.5 g and potassium acetate were 9.8 g. After stirring at 90 ° C for 3 hours, it was cooled to room temperature. The extraction was carried out using toluene and distilled water, and several layers were separated, dried, and concentrated under reduced pressure. The concentrate was column isolated, and A9-1 19.7 g (yield 81%) was obtained.
[0167] 2-2. Preparation of Compound A9-2
[0168] The compound A9-1 19.8 g (0.054 mol) prepared in Example 2-1 was placed in a 1000-mL 4-neck round bottom flask, and 400 ml of tetrahydrofuran was diluted wit...
Embodiment 3
[0173] [Example 3] Preparation of Compound A14
[0174]
[0175] 3-1. Preparation of Compound A14-1
[0176] 5-bromobenzene was placed in 500-mL 3 neck round bottom flask, and 11.5 g (0.054 mol) was placed, and 250 ml of tetrahydrofuran was diluted with tetrahydrofuran. After the dilution is placed in a diluent, 7.2 g of 3M-potassium carbonate solution 54 ml and tetrafi (triphenylphosphine) palladium (0) 1.0 g were refluxed for 4 hours. After cooling the reaction solution to room temperature, tetrahydrofuran was concentrated, and then methanol was added to precipitate solids and vacuum filtration. The aggregated solid compound was vacuum dried to obtain Compound A14-1 9.9 g (yield 87%).
[0177] 3-2. Preparation of Compound A14-2
[0178] Under a nitrogen atmosphere, compounds A14-112.2 g (0.058 mol) prepared in Example 3-1 were placed in a 500-mL 3 neck round bottom flask, and 200 ml of toluene was diluted with 200 ml of toluene. In this diluent, 4-bromine-1,1, 1 is added 13.5 ...
