Procedure

To a solution of N-(2-aminoethyl)-2-hydroxybenzamide (332 mg, 1.85 mmol), dimethoxyacetaldehyde (0.475 mL, 1.85 mmol) in CH2Cl2 (10 mL) was added sodium triacetoxyboro hydrid (588 mg, 2.80 mmol). The resulting mixture was stirred overnight, then diluted with EtOAc (50 mL), washed with 10 mL of water and then brine, dried over MgSO4, and conc in vacuo to yield 441 mg (97%) of the product as a colorless oil. MS (ESI) 269 (M+H).
