| Abstract: | Objective] To improve the synthesis technology of 4-(N-t-butoxycarbony)aminomethyl-1-(N-t-butoxycarbony)pyrrolidin-3-alcohol.Method] 4-(N-t-butoxycarbony)aminomethyl-1-(N-t-butoxycarbony)pyrrolidin-3-alcohol was synthesized starting from 4-cyano-1-(N-t-butoxycarbony)pyrrolidin-3-ketone by one-pot of reduction with NaBH4,hydrogenation reduction in the presence of Urushibara-Co and amino protection with Boc.Result] Experiment results showed the total yield increased from 75% to 88% by reduction of Urushibara-Co instead of LiAlH4 in the improved reduction reaction.Structure of the product was confirmed by 1HNMR.Conclusion] The synthesis technology is suitable for industrialization with operation safety. |
