An initial charge of 508 g (6.94 mol) of 1-butylamine is admixed dropwise over the course of 2.5 h with 171 g (1.00 mol) of chloropropyldimethylchlorosilane and the mixture is heated at reflux for 12 h. Following distillative removal of the excess 1-butylamine, the residue is diluted with 350 ml of toluene and cooled to 10° C. The precipitate it forms is filtered off and the filtrate is distilled in vacuo. This gives 134.5 g of N-butyl-1,1-dimethyl-1-sila-2-azacyclopentane.
