Vorschrift

357.7 g (1.68 mol) of 3,5-dinitrobenzoic acid are suspended in 750 ml of 1-methyl-2-pyrrolidone. The suspension is stirred up to 50° C. 386.4 g (4.60 mol) of sodium hydrogen carbonate are added and the mixture was heated up to 90° C. 22.50 g (0.150 mol) of sodium iodide and 204.0 ml (1.53 mol) of 6-chlorohexanol are added to the reaction mixture which is heated to 100° C. for 1 h. After 1 h of reaction, the reaction is complete and the orange suspension is thrown on 21 of ice and 11 of water. The product is filtrated, washed water and dried at 50° C. under vacuum for 24 h to give 425.0 g of 6-hydroxyhexyl 3,5-dinitrobenzoate as a rose powder.
