関与物質

反応手順

To a stirred solution of 3-(4-chlorophenyl)propanoic acid (commercially available from Maybridge) (14.5 g, 77.1 mmol) in methanol (400 ml) was added acetyl chloride (50 ml) and the reaction mixture was refluxed for 20 h. After this time the reaction mixture was left to cool before being concentrated under reduced pressure. The residue was then dissolved in DCM (200 ml) and washed with 1M sodium hydroxide solution (100 ml). The organic layer was dried with magnesium sulphate and concentrated in vacuo to give the title product as a brown oil (15.7 g, 77 mmol, 100%); 1HNMR (400 MHz, CDCl3) δ: 2.55 (t, 2H), 2.9 (t, 2H), 3.6 (s, 3H), 7.1 (d, 2H), 7.2 (d, 2H).
