Reaction Steps
A mixture of 2-[(3S,5S)-1-(tert-butoxycarbonyl)-5-(hydroxymethyl)pyrrolidin-3-ylamino]-N-(3,4-dimethoxylbenzyl)-5-nitrobenzamide (326 mg) and 4N-hydrogen chloride solution in ethyl acetate (5 mL) was stirred for one day at ambient temperature. After evaporation of the solvent, the residue was partitioned between chloroform and an aqueous saturated sodium bicarbonate solution. The organic layer was separated, washed with brine and dried over magnesium sulfate. The filtrate was evaporated to give N-(3,4-dimethoxylbenzyl)-2-[(3S,5S)-5-(hydroxymethyl)pyrrolidin-3-ylamino]-5-nitrobenzamide (242 mg) as pale yellow foams.
