Reaction Steps

To a solution of 3-(2-methylamino-phenoxy)-propionitrile (1.55 g, 8.8 mmol) and azidotributyltin (3.6 mL, 13.2 mmol) in toluene (30 mL) was added triethylaluminum (9.3 mL, 17.6 mmol, 1.9 M in toluene). The mixture was heated at 80° C. for 16 hrs. The mixture was diluted with water (100 mL) and ethyl acetate (200 mL). The ethyl acetate layer was separated and removed. The resulting methyl-{2-[2-(1H-tetrazol-5-yl)-ethoxy]-phenyl}-amine stayed in the aqueous solution and was used in the next step without purification. [M+H]+220.1; tR=0.388 min (method 1).
