Methyl iodide → (R)-3-[8-(3,4-difluoro-benzyloxy)-octanoylamino]-4-trimethylammonio-butyrate

Participants

Reaction Steps

Potassium hydrogencarbonate (24 mg, 0.24 mmol) and iodomethane (106 mg, 0.74 mmol) were added to a solution of (R)-3-[8-(3,4-difluoro-benzyloxy)-octanoylamino]-4-dimethylamino-butyric acid (77 mg, 0.19 mmol) in methanol (2.5 mL). The reaction mixture was stirred at room temperature for 16 h, then diluted with chloroform (5 mL). Insoluble material was removed by filtration to afford (R)-3-[8-(3,4-difluoro-benzyloxy)-octanoylamino]-4-trimethylammonio-butyrate as a light yellow solid, m/e=429.3 ([M+H]+).
