Embodiment 1
[0065]
[0066] First weigh compound M01 (29.3mg, 0.24mmol), K 2 CO 3 (27.6mg, 0.20mmol) and compound A01 (82.4mg, 0.20mmol) were added to the reaction tube, and the gas was purged three times through the vacuum line. Under nitrogen atmosphere, DCM (2.0mL) was added and reacted at room temperature for 24h. After the reaction was completed, the solvent was removed by rotary evaporation, and the sample was applied by dry method. Column chromatography (300-400 mesh chromatography silica gel) (petroleum ether-ethyl acetate=19:1) yielded 41.9 mg of product P01 with a yield of 91%.

Embodiment 2
[0071]
[0072] Weigh K first 2 CO 3 (27.6mg, 0.20mmol) and compound A01 (82.4mg, 0.20mmol) were added to the reaction tube, and the gas was purged three times through the vacuum line. Under nitrogen atmosphere, DCM (2.0mL) and compound M02 (14.4mg, 0.24mmol) were added , Reaction at room temperature for 24h. After the reaction was completed, the solvent was removed by rotary evaporation, and the sample was applied by dry method. Column chromatography (300-400 mesh chromatography silica gel) (petroleum ether-ethyl acetate=19:1) yielded 21.6 mg of product P02 with a yield of 64%.

[0074] 13 C NMR (100MHz, CDCl 3 )δ (ppm): 171.29, 147.07, 115.26, 60.81, 37.14, 29.14, 28.46, 27.86, 26.74, 21.25;
[0075] HRMS-ESI(m / z): 169.1225[M+H] + .
Embodiment 3
[0077]
[0078] Weigh K first 2 CO 3 (27.6mg, 0.20mmol) and compound A01 (82.4mg, 0.20mmol) were added to the reaction tube, and the gas was purged three times through the vacuum line. Under nitrogen atmosphere, DCM (2.0mL) and compound M03 (11.0mg, 0.24mmol) were added , Reaction at room temperature for 24h. After the reaction was completed, the solvent was removed by rotary evaporation, and the sample was applied by dry method. Column chromatography (300-400 mesh chromatography silica gel) (petroleum ether-ethyl acetate=19:1) yielded 22.8 mg of product P03 with a yield of 74%.
[0079] 1 H NMR (400MHz, CDCl 3 )δ(ppm): 8.06(s, 1H), 5.31(tt, J=7.4, 1.3Hz, 1H), 4.68(d, J=7.4Hz, 2H), 2.21(t, J=5.5Hz, 2H) , 2.16-2.09(m, 2H), 1.56(h, J=4.2Hz, 7H);
