Reaction Steps

To a solution of N-(3,4-dimethoxylbenzyl)-2-[(R)-1-methoxycarbonyl-3-(methylthio)propylamino]-5-nitrobenzamide (175 mg) in anhydrous tetrahydrofuran (3 mL) were added lithium chloride (31 mg), and then sodium borohydride (28 mg) in ethanol (3 mL) at ambient temperature. The mixture was stirred for one day. After evaporation of the solvent, the residue was partitioned between ethyl acetate and 10% citric acid aqueous solution. The separated organic layer was washed with water and brine and dried over magnesium sulfate. The residual solid was recrystallized from ethyl acetate-hexane to give N-(3,4-dimethoxylbenzyl)-2-[(R)-1-hydroxymethyl-3-(methylthio)propylamino]-5-nitrobenzamide (122 mg).
