To a 1 neck round bottom flask equipped with stir bar and dropping funnel capped with a nitrogen outlet was added hexamethylenediamine (HMDA) (20 g, 0.17 mol). A 55% aqueous solution of the mixture of 2-nitro-2-ethyl-1,3-propanediol and 2-ethyl-2-nitrobutanol (189 g, 0.69 mol) was added drop wise to the flask over a period of 1 h with continuous stirring. After complete addition, the dropping funnel was replaced by a condenser and the reaction mixture refluxed for 6 h and stirred at room temperature overnight. After completion of the reaction, the content of the flask was filtered through suction filtration and the deep red high viscous material was collected and dried under vacuum for 8 h. The molecule was too bulky to be detected in GC/MS. The sample was passed through the HPLC Column (90/10 water/acetonitrile) and it showed the formation of three different products. The HPLC retention times recorded were 1.27, 1.66 and 1.91 minutes, with the most polar compound i.e., retention time 1.27 min was formed in greatest amount.
