(4-chlorophenyl) propanoate

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into a mixture of p-chlorophenol (20.0 g, 156 mmol), pyridine (14.8 g, 187 mmol), and toluene (150 ml), propionic acid chloride (17.3 g, 187 mmol) was added dropwise, and the resultant mixture was stirred for 1 hour at room temperature. Water (150 ml) was added and the aqueous layer was discarded. The organic layer was concentrated and distilled under reduced pressure (bp. 73°-76° C./0.2 mmHg), thereby obtaining a propionic acid-p-chlorophenyl ester (25.6 g, 138 mmol, 89%). was added dropwise The organic layer was concentrated distilled under reduced pressure (bp. 73°-76° C./0.2 mmHg)
