Parratt, Martin John, US2003/18197, A1, (2003) A solution containing 7.9 ml of hydrazine hydrate in 80 ml of ethanol was treated with 3.7 ml of 4-m ethoxybenzylchloride and heated at 90°C. for 2.0 h. The solvent was reduced by evaporation under re duced pressure and then the resulting residue was dissolved in 30 ml of ethanol. The solution was ac idified with 30 ml of 5N HCl at 0°C. and a white precipitate separated. The white solid was filtere d off and dried to give 2.75 g of (4-methoxybenzyl)hydrazine dihydrochloride (PMBNHNH2.2HCl), which was used without further purification.
