Trifluoroacetic acid → HCID 178515443、化合物

Into a 100-mL round-bottom flask, was placed a solution of [4-bromo-2-(tert-butoxy)quinolin-6-yl]bis(4-chlorophenyl)methanol (1.5 g, 2.82 mmol, 1.00 equip) in dichloromethane (55 mL), Et3SiH (1.3 g, 4.00 equip), and trifluoroacetic acid (8 g, 70.77 mmol, 25.00 equip). The resulting solution was stirred overnight at room temperature. The pH value of the solution was adjusted to 7-8 with sodium bicarbonate. The resulting solution was extracted with DCM (3×50 ml) and the organic layers combined. The resulting mixture was washed with water (2×50 mL). The resulting mixture was washed with brine (1×50 mL). The resulting mixture was dried over anhydrous sodium sulfate and concentrated to yield 6-[bis(4-chlorophenyl)methyl]-4-bromoquinolin-2-ol as a white solid. (ES, m/z): [M+H]+ 433
