实验步骤: tert-Butyl ((5-(cyclo ex-1-en-1-yl)-1-((3-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 7d (100 mg, 0.22 mmol) was dissolved in 20 mL of N,N-dimethylformamide, followed by addition of cesium carbonate (146 mg, 0.45 mmol) and 2-bromo-N-cyclopropyl-acetamide (79 mg, 0.45 mmol, prepared by a known method disclosed in “Journal of Medicinal Chemistry, 1987, 30(1), 20-24”), and then the reaction solution was stirred for 16 h. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by thin layer chromatography with elution system C to obtain the title product tert-butyl ((5-(cyclohex-1-en-1-yl)-1-((3-(2-(cyclopropylamino)-2-oxoethoxy)phenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 7e (117 mg, a light yellow oily product) in 98% yield. prepared by a known method The reaction solution was concentrated under reduced pressure the resulting residue was purified by thin layer chromatography with elution system C

实验步骤: tert-Butyl ((5-(2-fluorophenyl)-1-((3-hydroxyphenyl)sulfonyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 1h (100 mg, 0.22 mmol) was dissolved in 20 mL of N,N-dimethylformamide, followed by addition of cesium carbonate (215 mg, 0.66 mmol) and 2-bromo-N-cyclopropyl-acetamide (61 mg, 0.34 mmol, prepared by a known method disclosed in “Journal of Medicinal Chemistry, 1987, 30(1), 20-24”) and then the reaction solution was stirred for 16 h. 50 mL of water were added, and the reaction solution was extracted with dichloromethane (50 mL×3). The organic phases were combined, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure to obtain the title product tert-butyl ((1-((3-(2-(cyclopropylamino)-2-oxoethoxy)phenyl)sulfonyl)-5-(2-fluorophenyl)-1H-pyrrol-3-yl)methyl)(methyl)carbamate 3a (100 mg, a yellow oil), which was used directly in the next step. prepared by a known method the reaction solution was extracted with dichloromethane (50 mL×3) dried over anhydrous sodium sulfate filtered the filtrate was concentrated under reduced pressure

实验步骤: 12-3 (0.2 g, 0.39 mmol) and 2-bromo-N-cyclopropylacetamide 38-1 (0.069 g, 0.39 mmol) were suspended in chloroform/2M Na2CO3 in a sealed tube and heated in a Smith Personal Chemistry microwave reactor at 100° C. for 20 minutes. The solid was then filtered off and purified on a silica column to afford 38-2. Hi-Res MS: calc: 385.1554 found: 385.1548. 1H-NMR (CD3OD): 8.39(s, 1H); 7.99(s, 1H); 6.14(s, 1H); 3.68(m, 4H); 3.05(s, 2H); 2.70(m, 1H); 2.58(m, 4H); 0.75(m, 2H); 0.55(m, 2H). The solid was then filtered off purified on a silica column to afford 38-2
