Procedure

A solution of 580 mg of 4-[2-hydroxy-3-(octadecyloxy)-propoxy]-N,N,N-trimethyl-1-butanaminium bromide in 5 ml of acetic anhydride is stirred at reflux under inert gas for 15 minutes. Toluene is added and the solvents evaporated followed by several additional toluene evaporations. The residue is stirred with ether and stored at 0° C. for several days. The resulting solid is collected and dried to give 480 mg of the desired product.
