(3-bromo-2-chlorophenyl)methanol

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

実験手順: To a flask charged with (3-bromo-2-chlorophenyl)methanol (1.1 g, 4.8 mmol) and a stir bar was added thallium trifluoroacetate (2.9 g, 5.3 mmol) and TFA (6 mL). The mixture was allowed to stir at RT for 16 hours. The volatiles were removed under reduced pressure. The residue was pumped under high vacuum for 15 minutes before palladium (II) chloride (0.085 g, 0.48 mmol), magnesium oxide (0.39 g, 9.6 mmol), lithium chloride (0.20 g, 4.8 mmol), and ethanol (30 mL) were added. The mixture was stirred under an atmosphere of carbon mono-oxide until the reaction turned black. The reaction was diluted with DCM. The suspension was filtered through a pad of Celite® to remove the solids. The filtrate was adsorbed onto silica gel, and purified by MPLC to afford 5-bromo-4-chloro-2-benzofuran-1(3H)-one. LC-MS (IE, m/z): 249 [M+1]+; The volatiles were removed under reduced pressure were added The mixture was stirred under an atmosphere of carbon mono-oxide until the reaction The suspension was filtered through a pad of Celite® to remove the solids purified by MPLC

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

実験手順: To a solution of methyl 3-bromo-2-chlorobenzoate (1.9 g, 7.6 mmol) in THF (30 mL) was added Super Hydride (23 mL, 23 mmol) at 0° C. The reaction was allowed to stir for 16 hours. TLC showed clean reaction. The reaction was diluted with EtOAc, washed with brine, dried over sodium sulfate, and purified by MPLC to furnish (3-bromo-2-chlorophenyl)methariol. LC-MS (IE, m/z): 205 [M-17]+; reaction washed with brine dried over sodium sulfate purified by MPLC
