Versuchsvorschrift

N-trityl-1-[4-(benzoxazol-2-yl)benzyloxy]-3-hydroxy-2-propanamine (0.4 g; 0.74 mmol) is added to a suspension of potassium hydride (0.12 g; 1. mmol; 35% suspension in oil) in dry THF (4 ml) at 0° C. The reaction is stirred for 15 minutes at 20° C. 4-Phenyl-1-butyl iodide (0.21 g; 0.81 mmol) is added and the reaction mixture stirred for 15 hours. The reaction is quenched with MeOH, diluted with CH2Cl2 and washed with water 2x. The organic phase is dried (Na2SO4), concentrated and purified by column chromatography with 80% CH2Cl2 /20% petroleum ether to yield N-trityl-1-[4-(benzoxazol-2-yl)benzyloxy]-3-(4-phenylbutoxy)-2-propanamine as an oil which is used directly in Step F.
