Triethylamine → Methyl 3-(2-(dichlorophosphoryloxy)phenyl)propanoate

Participants

Reaction Steps

Dry triethylamine (0.38 mL, 2.8 mmol) and methyl 3-(2-hydroxyphenyl)propanoate, 80 (0.5 g, 2.77 mmol) in dry ether (9.2 mL) were added dropwise to a solution of dry ether (5 mL) containing phosphorus oxychloride (0.25 mL, 2.8 mmol) at −78° C. under nitrogen. Following the addition, the reaction mixture was slowly allowed to warm to rt, and stirred for 1 h. The solvent was removed under reduced pressure to give crude product as an oil containing a significant amount of solid.
