Participants

Reaction Steps

The crude dioctadecylcyanamide (38 g) was suspended in 2.75 M H2SO4 (150 mL) and the mixture was refluxed for 2.5 h. After cooling to room temperature H2O (100 mL), 30% NaOH (100 mL) and CHCl3 (300 mL) were added. The organic phase was separated, dried and evaporated. The solid residue was suspended in Et2O and stirred for 1 h. The solid was filtered and washed with to give the desired compound (15.3 g; 29.3 mmol). Yield 48%. K.F.: 0.20%. The 1H-NMR, 13C-NMR, MS and IR spectra were consistent with the structure.
