Procedure

A solution of 5.00 g (31.6 mmol) of nonanoic acid, 3.93 g (34.76 mmol) of chloroacetyl chloride (CAC), 2.97 g (31.6 mmol) of phenol, and 35 mL of acetonitrile was delivered to a clean, dry, two neck 100 mL round bottom flask fitted with a mechanical stirrer and a reflux condenser. The reaction flask was flushed with nitrogen through a gas inlet at the top of the reflux condenser and placed in an 80° C. oil bath and stirred for 19 hours. The reaction mixture was allowed to cool to room temperature and then vacuum filtered through 30 g of neutral alumina to remove chloroacetic acid. The purified product was then placed on a high vacuum line overnight to remove any residual solvent. Phenyl nonanoate (NOB) was isolated as a faint yellow liquid (6.18 g, 26.37 mmol) in 83% yield. The purity of NOB was determined to be over 97%.
