Procedure

A solution of N, N, N-tris[[[(2-hydroxyphenyl)methylene]amino]ethyl]amine (40.0 g, 87 mmol) in 250 mL of methanol and 250 mL of methylene chloride was cooled in an ice bath. Sodium borohydride (10.0 g, 263 mmol) was added in several portions. Stirring was continued at room temperature for two hours. The solvents were evaporated and the residue was taken up in ether. This solution was washed with water and brine, dried over magnesium sulfate, filtered and evaporated to afford N, N, N-tris[[[(2-hydroxyphenyl)methyl]amino]ethyl]amine(30.0 g, 74%) as a colorless glass.
