実験手順
32.5 ml (0.45 mol) of thionyl chloride and 10 μl of N,N-dimethylformamide are added to a solution of 20.0 g (89.2 mmol) of [3-(ethoxycarbonyl)phenoxy]acetic acid (A. Banerjee, M. M. Adak, S. Das, S. Banerjee, S. Sengupta, Indian Chem. Soc., 1987, 64, 1, 34-37) in 200 ml of 1,2-dichloroethane. The mixture is refluxed for 1 hour and is then concentrated to dryness and dried under vacuum at 50° C. overnight and used as it is in the subsequent stage.
