Trimethylsilyldiazomethane → Methyl 4-amino-2-fluoro-5-methoxybenzoate

Participants

Reaction Steps

To an amount of 4-amino-2-fluoro-5-methoxybenzoic acid (4 g, 21.62 mmole) that was dissolved in DCM (40 ml) and MeOH (11 mL), was added TMS-diazomethane (16.2 mL, 32.43 mmole) slowly. The mixture was stirred at r.t for 30 mins. After the removal of solvent, the resulting tan solid (4.0 g, 93%) carried onto the next reaction without any purification. [M+H] calc'd for C9H10FNO3, 200. found 200.
