(2-amino-5-bromo-4-chlorophenyl)methanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A mixture of (2-amino-5-bromo-4-chlorophenyl)methanol (6 g, 25.5 mmol) and manganese(IV) oxide (15.5 g, 0.178 mol) in dichloromethane (100 mL) was stirred at room temperature overnight. The solid was filtered off, and the filtrate was concentrated to give the title compound as a light yellow solid (5 g, 81%). MS (ES+) C7H5BrClNO requires: 233, 235, found: 234, 236 [M+H]+. The solid was filtered off the filtrate was concentrated

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of 2-amino-5-bromo-4-chlorobenzoic acid (9.0 g, 36.0 mmol) in THF (150 mL) was added borohydride in THF (144 mL, 1 M) at room temperature, and the reaction mixture was stirred overnight. The reaction mixture was quenched with methanol (50 mL), and concentrated to a volume of 50 mL. The residue was diluted with water (100 mL) and extracted with ethyl acetate (150 mL×3). The organic layers were separated, combined, washed with water (100 mL) and brine (100 mL), dried over sodium sulfate, filtered and concentrated to afford the title compound (crude, 6 g, 71%). The reaction mixture was quenched with methanol (50 mL) concentrated to a volume of 50 mL The residue was diluted with water (100 mL) extracted with ethyl acetate (150 mL×3) The organic layers were separated washed with water (100 mL) and brine (100 mL) dried over sodium sulfate filtered concentrated

実験手順: (2-amino-5-bromo-4-chlorophenyl)methanol (8.2 g, 34.7 mmol), 3,5-dimethylacetophenone (8.22 g, 55.5 mmol), RuCl2(PPh3)3 (0.15 g, 0.173 mmol), and KOH (1.31 g, 23.4 mmol) was refluxed in 90 mL of toluene for 18 hours. Water was collected from the reaction using a Dean-Stark trap. The reaction mixture was allowed to cool to room temperature and filtered through a silica gel plug and eluted with DCM and purified by column chromatography, eluting with 2:1 (v/v) hexanes:DCM, to give 6-bromo-7-chloro-2-(3,5-dimethylphenyl)quinoline (5.2 g, 43.3%). Water was collected from the reaction filtered through a silica gel plug eluted with DCM purified by column chromatography eluting with 2:1 (v/v) hexanes
