Participants

Reaction Steps

In a 10 ml round-bottomed flask, 0.25 g of 4-(2,4-bis(benzyloxy)phenyl)piperidine is dissolved in 5 ml of tetrahydrofuran in the presence of 0.23 ml of N,N-diisopropylethylamine. 0.08 ml of butyl isocyanate is added and the reaction mixture is then stirred for 20 minutes at ambient temperature. The reaction mixture is extracted with ethyl acetate, and then the organic phases are combined and dried over magnesium sulphate. The residue is chromatographed on silica gel (8/2 heptane/ethyl acetate). 0.25 g of 4-(2,4-bis(benzyloxy)phenyl)piperidine-1-carboxylic acid butylamide is obtained. Yield=78%.
