A mixture of 9.43 g of phenyl ethenesulfonate and 4.60 ml of 2-nitro-propane was heated to 80° C. and, at 80° C., 0.89 ml of ethyidiisopropylamine was added dropwise. The mixture was stirred at 80° C. for 4 hours and 30 minutes, left to stand at RT for 16 hours and then stirred at 80° C. for a further 2 hours. Cooling to RT was followed by addition of 250 ml of a 2N aqueous HCl solution and extraction 3 times with 150 ml of EA each time. Drying over Na2SO4 and removal of the solvent in vacuo were followed by coevaporation 3 times with 100 ml of toluene each time. 13.47 g of a pale yellow oil were obtained.
