[OH-].[Na+].[N+:3]([C:6]1[CH:11]=[CH:10][CH:9]=[CH:8][C:7]=1[OH:12])([O-:5])=[O:4].Cl[CH2:14][CH:15]=[CH2:16].CS(C)=O>O>[CH2:16]([O:12][C:7]1[CH:8]=[CH:9][CH:10]=[CH:11][C:6]=1[N+:3]([O-:5])=[O:4])[CH:15]=[CH2:14]A solution of 64 g of sodium hydroxide in 75 ml of water was added drop-by-drop (over 15 minutes) to a stirred mixture of 209.6 g of 2-nitrophenol, 115.5 g of 3-chloropropene and 500 ml of dimethyl sulfoxide (DMSO), at room temperature. The mixture was stirred at 85°-90° C. for 18 hours and then mixed with 3 liters of water. The resulting mixture was extracted with methylene chloride, the extract was washed with ice water, dried (MgSO4) and the solvent was evaporated, to give 1-(2-propen-1-yloxy)-2-nitrobenzene (1A), as an amber syrup.
