2-Hydroxy-6-(1-(3-phenylurylphenyl)ethoxy)-benzaldehyde ($mathbf{2}$) has been synthesized in racemic form from 1,3-Dihydroxybenzene via formylation and reaction with 3-phenyluryl-methylbenzylbromide. The optically pure form of $mathbf{2}$ was separated by normal silica column chromatography from the imine diastreomer which was obtained by the reaction of racemic mixture of $mathbf{2}$ with optically pure leucinol. The absolute configuration of the separated enantiomer of $mathbf{2}$ was decided from the energy calculation of the corresponding imine diastereomers. The activity of $mathbf{2}$ as a chirality conversion reagent (CCR) for amino acids was determined by $^1H$ NMR analysis. The efficiency of $mathbf{2}$ is not better than the previous CCRs based on binaththol. Compound $mathbf{2}$, however, has lower molecular weight compared to other CCRs. This work demonstrates that asymmetric carbon can control the selectivity of amino acids.
