実験手順

1.53 g of a mixture of 2-chlorodioxene and 2,2-dichlorodioxane (molar ratio 1:1) are added to 1.00 g (7.24 mmol) of 4-nitroaniline, and the mixture is heated to 80° C. with stirring. A solid brown mass forms within one hour and becomes liquid again and crystallises within the following 12 hours. The crude product is recrystallised from ethanol with addition of water, giving 1.80 g of 2-(2-chloroethoxy)-N-(4-nitrophenyl)acetamide (“A1”) as yellowish crystals, m.p. 101-102° C. 1H-NMR (d6-DMSO): δ=3.82 (m; 4H), 4.23 (s; 2H), 7.91 (d, J=9 Hz, 2H), 8.23 (d, J=9 Hz, 2H), 10.34 (s, 1H).
