To this mixture was added dropwise a solution of 1.0 g of 2-(benzylimino-methyl)-phenol in 3 mL of 2-propanol. After complete addition, stirring was continued for 1 h. Then water was added in order to decompose excess borohydride, and the volatiles were removed in vacuo. The residue was redissolved in ethyl acetate, washed with water, dried (sodium sulfate) and concentrated yielding 0.9 g of 2-(benzylamino-methyl)-phenol as an oil. EI-MS: 213 (M+).
