Triethylamine → Ethyl 6-chloro-2-fluoro-3-(pivalamidomethyl)benzoate

Participants

Reaction Steps

To a solution of ethyl 3-(aminomethyl)-6-chloro-2-fluorobenzoate (70 mg, 0.3 mmol) in THF (3 mL) were added Et3N (0.105 mL, 0.76 mmol) and pivaloyl chloride (38 μL, 0.31 mmol). The reaction mass was stirred at rt for 2 h, diluted with EtOAc and was washed with water, and brine. The organic layer was separated, dried, filtered and concentrated to afford 70 mg of the title product. 1H NMR (300 MHz, DMSO-d6): δ 8.15 (br t, 1H), 7.43-7.35 (m, 2H), 4.38 (q, J=7.2 Hz, 2H), 4.26 (d, J=5.7 Hz, 2H), 1.30 (t, J=6.9 Hz, 3H), 1.11 (s, 9H).
