Participants

Reaction Steps

Whilst carrying out external cooling with ice water a solution of 44.3 g (0.2 mol) of 2-nitrobenzenesulphonyl chloride in 250 ml of chloroform was added dropwise to a solution of 38.0 g (0.2 mol) of 4-amino-1-(phenylmethyl)piperidine and 22.0 g (0.22 mol) of triethylamine in 250 ml of chloroform. After the cooling was stopped the mixture was stirred for a further 30 minutes at room temperature, the reaction mixture was then extracted twice with 1 l water. The aqueous extracts were extracted once more with 100 ml of dichloromethane, the combined organic phases were then dried over sodium sulphate and evaporated down in vacuo. The highly viscous light-brown substance obtained in a yield of 75.0 g (99.9% of theory) was further processed without any more purification.
