Reaction Steps

Into a 100-mL round-bottom flask was placed a solution of 4-[4-(methylcarbamoyl)phenyl]phenyl 2,5-dioxopyrrolidin-1-yl carbonate from Example 1 Step 4 (560 mg, 1.5 mmol, 1 equiv) in dichloromethane (40 mL), N-methyl (3-biphenyl)methylamine (301 mg, 1.5 mmol, 1 equiv) and triethylamine (153 mg, 1.5 mmol, 1 equiv). The resulting solution was stirred overnight at room temperature. The reaction mixture was washed with 2×20 mL of water and dried over anhydrous sodium sulfate. The resulting mixture was concentrated under vacuum. The crude product (650 mg) was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-002(Agilent)): Column, SunFire Prep C18, 19*150 mm 5 um; mobile phase, water and acetonitrile (10.0% acetonitrile up to 80.0% in 10 min, up to 100.0% in 1 min, down to 10.0% in 2 min); Detector, uv 220 & 254 nm. The title compound was obtained as a white solid.
