Embodiment 1
[0021] The preparation of embodiment 1 compound (III-1):
[0022] 2-Amino-4-dimethylamino-1,3,5-triazine (121.3mg, 0.87mmol), phenylacetonitrile 5a (200.3mg, 1.71mmol), CuBr (24.8mg, 0.17mmol) in o-di Mix in chlorobenzene (2.0mL), react at 125°C for 15h, after the reaction, add 50mL of water, extract with dichloromethane (20mL×3), combine the organic layers, dry with anhydrous sodium sulfate, filter, Concentrate, column chromatography (eluent is CH 2 Cl 2 : MeOH=30:1, V:V), collect R f The eluate with a value of 0.3-0.35 (monitored by TLC, the developing solvent is the same as the eluent), the solvent was distilled off under reduced pressure, and dried to obtain 169.2 mg of the target compound (III-1), with a yield of 80%. 1 H NMR (500MHz, CDCl 3 ):δ8.65(s,1H),8.38(s,1H),7.90-7.88(m,2H),7.60-7.56(m,1H),7.51-7.48(m,2H),3.21(s,3H ),3.19(s,3H)
[0023]
Embodiment 2
[0025] Change cuprous chloride to cuprous bromide (10.8mg, 0.07mmol), change the temperature to 135°C, and change the time to 30h. Other operations are the same as in Example 1. The yield is 137.5mg, and the yield is 65%.
Embodiment 3
[0027] Dichlorobenzene was changed to chlorobenzene (9 mL), the temperature was changed to 80° C., other operations were the same as in Example 1, and the yield was 52.9 mg, with a yield of 25%.
