Participants

Reaction Steps

In a 10 ml round-bottomed flask, 0.25 g of 3-(2,4-bis(benzyloxy)phenyl)pyrrolidinium trifluoroacetate is dissolved in 5 ml of tetrahydrofuran in the presence of 0.25 ml of N,N-diisopropylethylamine. 0.1 g of cyclohexyl isocyanate is added and the reaction mixture is stirred for 30 minutes at ambient temperature. The reaction mixture is extracted with ethyl acetate and the organic phases are then combined and dried over magnesium sulphate. The residue is chromatographed on silica gel (7/3 heptane/ethyl acetate). 0.23 g of 3-(2,4-bis(benzyloxy)phenyl)pyrrolidine-1-carboxylic acid cyclohexylamide is obtained. Yield=66%.
