M-Cresol → HCID 51924569, compound

Participants

Reaction Steps

To a solution of the m-cresol (1.0 g, 9.2 mmol) in anhydrous THF (15 mL) at 0° C. under argon protection was added triphenylphosphine (2.55 g, 9.7 mmol), followed by addition of the (S)-methyl 2-hydroxypropanoate (926 μL, 9.7 mmol). Then diisopropylazodicarboxylate (DIAD) (2.85 mL, 13.8 mmol) was added dropwise at 0° C. The reaction mixture was stirred at room temperature overnight. The resulting mixture was diluted by ethyl acetate, washed with a 0.5 N HCl solution, a saturated solution of NaHCO3, and brine, dried on MgSO4, and concentrated. The obtained oil was purified by flash chromatography (Hexane/Ethyl acetate 0˜50%) to afford a colorless oil (820 mg, 46%).
