Embodiment 1
[0074]
[0075] The synthetic method of compound 2 is as follows:
[0076]
[0077] Under nitrogen protection, compound 1-a (1.1eq, 9.5g, 375.28g / mol, 25.41mmol) and compound 1-b (1eq, 10g, 432.90g / mol, 23.10mmol) were dissolved in 200mL toluene, and acetic acid was added Palladium (0.26g, 224.51g / mol, 1.16mmol), X-phos (0.26g, 476.72g / mol, 1.16mmol), potassium carbonate (9.58g, 138.21g / mol, 69.3mmol), then add 100mL ethanol and 50mL of water was stirred overnight at 82°C, and the reaction progress was monitored by HPLC.
[0078] After the complete reaction of compound 1-b was monitored by HPLC, the reaction was stopped, the reaction solution was cooled to room temperature, 60 mL of water was added, stirred for 20 min, and the filter cake was obtained by suction filtration. The filter cake was rinsed twice with water and ethanol and then dried in vacuum at 80°C for 6 hours. Add the dried filter cake to a 250mL three-necked flask, add 100mL of o-dichlorobenzene, and heat...
Embodiment 2
[0080]
[0081] The synthetic method of compound 5 is as follows:
[0082]
[0083] The preparation method is basically the same as in Example 1, the difference is that compound 1-a is replaced by compound 2-a to obtain the final target product compound 5 (9.2g, yield 61.3%), ESI-MS (m / z) (M+ ): theoretical value 645.76, measured value 646.15, elemental analysis results (molecular formula C45H23D5N4O): theoretical value C, 83.70; H, 5.15; N, 8.68; O, 2.48; measured value C, 83.71; H, 5.14; N, 8.62; O, 2.53.
Embodiment 3
[0085]
[0086] The synthetic method of compound 6 is as follows:
[0087]
[0088] The preparation method is basically the same as in Example 1, the difference is that compound 1-a is replaced by compound 3-a, compound 1-b is replaced by compound 3-b, and the final target product compound 6 (9.7g, yield 65% ), ESI-MS (m / z) (M+): theoretical value 645.76, measured value 646.02, elemental analysis results (molecular formula C45H23D5N4O): theoretical value C, 83.70; H, 5.15; N, 8.68; O, 2.48; measured value C, 83.68; H, 5.17; N, 8.70; O, 2.45.
