2-Methylbenzamide → Ethyl 2-methyl-benzimidate tetrafluoroborate

Participants

Reaction Steps

To a degassed suspension of o-toluamide (1.35 g, 9.788 mmol) in methylene chloride (5 mL) was added triethyloxonium tetrafluoroborate (9.788 mL, 9.788 mmol, 1 M in methylene chloride). After the clear solution was stirred at room temperature overnight, it was concentrated in vacuo. The residue was triturated in methylene chloride and diethyl ether. The white solid was filtered off and washed with diethyl ether to afford ethyl 2-methyl-benzimidate tetrafluoroborate (1.4 g, 80%). It was used without further purification.
