The reaction mixture is stirred for 15 hours at reflux. The solvent is evaporated and the residue taken up in methylene chloride. The organic phase is then washed with water, dried and evaporated. The residue contains the desired product methyl-tris(tris(trimethylsiloxy)silylpropyl)ammonium iodide (31); 1H-NMR (ppm, CDCl3): 3.27 6H t, 3.18 3H s, 1.56-1.50 6H m, 0.37 6H t, 0 81H s.
