Embodiment 1
[0034] Example 1 (S)-4-amino-6-((1-(8-chloro-4-oxo-2-phenyl-1,4-dihydroquinolin-3-yl)ethyl)amino) Preparation of pyrimidine-5-cyanomethanesulfonate
[0035] Step 1: Preparation of 3-chloroisatoic anhydride
[0036]
[0037] Add 2-amino-3-chlorobenzoic acid (34.2g, 0.2mol) and 175mL of acetonitrile in a 500mL three-necked flask, cool down to 0°C, then add dropwise a dichloromethane solution of triphosgene (triphosgene (29.6g, 0.1 mol) was dissolved in 150 mL of dichloromethane), and pyridine (50 mL, 0.6 mol) was added dropwise at the same time, and the dropwise addition was completed in about 30 minutes, and the reaction was tracked by TLC until the reaction was complete. After treatment, spin dry directly, add water to make a slurry, and filter to obtain the title compound.
[0038] Step 2: Preparation of 3-acetyl-8-chloro-2-phenylquinolin-4(1H)-one
[0039]
[0040] Add 1-phenyl-1,3-butanedione to the reaction flask, add N,N-dimethylformamide, add sodium methoxide to...
