Reaction Conditions:

with N-ethyl-N,N-diisopropylamine in dichloromethane at 13;Cooling with ice;

Steps:

3.3.1

In a 500 mL reaction flask, IM6-1 (16.672 g, 98 mmol), 200 mL of DCM, and DIPEA (35 mL, 202 mmol) were sequentially added.Stir to dissolve, cool in ice bath,CH3COCl (7.2 mL, 101 mmol) was added dropwise,The reaction was stirred at 13 ° C, and the reaction progress was monitored by TLC-ninhydrin colorimetry.At the end of the reaction for 7.3h, suction filtration was performed under reduced pressure, and the filter cake was washed with DCM (5mL × 3).Collect the washings and filtrate, evaporate to dryness under reduced pressure (yellow oily liquid), stir with 70mL of EtOAc, suction filter under reduced pressure, wash the filter cake with EtOAc (5mL × 3),Collect the washing liquid and filtrate, evaporate to dryness under reduced pressure (yellow oily liquid),Purification by batch column chromatography (CH3OH: DCM = 1: 9 (volume ratio)),The eluate was collected, evaporated to dryness under reduced pressure, and the purity was checked by TLC-ninhydrin colorimetric method.Vacuum drying to obtain a white powdery solid IM6-215.894g, yield 92%,
