Boron tribromide → HCID 10238624, compound

Participants

Reaction Steps

To a stirred solution of 2-benzyl-4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methylpentanoic acid (1-oxo-1,3-dihydroisobenzofuran-5-yl)amide (25 mg, 0.053 mmol) in anhydrous methylene chloride (1 mL) and cooled in ice was added boron tribromide (0.3 mL of 1 M solution in methylene chloride, 0.3 mmol). The reaction was stirred at room temperature for 3 hours and then quenched with water (5 mL). Methylene chloride (25 mL) was added, the organic layer separated, dried over anhydrous sodium sulfate and concentrated in vacuo to give a light brown oil which was purified by preparative TLC eluting with methylene chloride-EtOAc (9:1) to give the title compound as a light, cream colored solid.
