Acetic Acid → HCID 11150086, compound

Participants

Reaction Steps

Compound 22 (101 mg, 0.200 mmol) was dissolved in tetrahydrofuran (10 ml), and a solution of 1-M tetrabutylammonium fluoride in tetrahydrofuran (0.42 ml, 0.42 mmol) was added to the resultant solution, followed by stirring at room temperature for five minutes. After acetic acid (24 μl) was added to the resultant reaction mixture, the resultant mixture was concentrated under reduced pressure. The thus-obtained residue was purified by means of silica gel column chromatography (silica gel 15 ml, chloroform methanol=40:1 to 20:1), to thereby yield compound 23 (53.0 mg, 0.191 mmol, 95.7%).
