Reaction Steps

In a flask equipped with a reflux condenser and a magnetic stirring bar are dissolved the methyl 5-benzyloxy-2-hydroxybenzoate and one equivalent of 2-(S)-amino-3-phenyl-1-propanol in dry dimethyl formamide. The flask is immersed in an oil bath at 75° C. and left to stir for 72 hours. The solvent is evaporated and the residue is isolated through the use of a silica gel column using a mixture of ethyl acetate and hexane as eluent. In this fashion is obtained in 50% yield, N-{(S)-1-hydroxy-3-phenyl-2-propyl}-5-benzyloxy-2-hydroxybenzamide.
