Embodiment 1
[0077] The preparation of embodiment 1 compound I-1
[0078] first step:
[0079]
[0080] Add 40g of raw material i into a 2L single-necked bottle, add 800mL of dichloromethane to dissolve it, then add 38.6g of triethylamine, add 32.6g of methanesulfonyl chloride dropwise at low temperature, and return to room temperature for reaction after dropping. After the reaction was completed, it was washed twice with 1 mol / L hydrochloric acid, once with saturated sodium chloride, dried over anhydrous sodium sulfate, and spin-dried to obtain 55 g of a brown-red oily liquid.
[0081] Step two:
[0082]
[0083] Add 64.6g of intermediate II and 180ml of DMF into a 2L single-necked bottle, add 41.6g of III after dissolving, then add 74g of cesium carbonate, and heat the oil bath until the external temperature is 105°C. After the reaction was completed, a large amount of water was added, extracted with ethyl acetate, spin-dried and separated by column chromatography to obtain 50 g ...
Embodiment 2
[0092] The preparation of embodiment 2 compound Ⅰ-2
[0093]
[0094] Add 1.0g of intermediate VI and 0.62g of cyclopropyl-piperazin-1-yl-methyl ketone into a 100mL one-necked bottle, then add 10mL of DMF and stir to dissolve, then add 2.05g of HBTU, 0.82g of triethylamine, and react at room temperature for 5h . After the reaction, the reaction solution was poured into water, extracted with ethyl acetate, dried with anhydrous sodium sulfate and spin-dried, and separated by column chromatography to obtain 1.1 g of solid.
[0095] 1 HNMR(DMSO-d6)δ:8.34(1H,s),8.05(1H,s),7.18~7.15(1H,m),6.97~6.92(1H,m),6.51~6.46(1H,q),3.67 ~3.60(8H, m), 2.54(3H, s), 2.11(3H, d, J=7.2Hz), 1.66~1.64(1H,m), 0.94~0.86(2H,m), 0.73~0.71(2H ,m).
[0096] m / z=505(M+H+)
[0097] The preparation of Examples 3-32 refers to the process route above in the specification, and the preparation process of the compound is similar to that of Example 1 and Example 2. Table 1 below shows the test data of the e...
