26 g (83 mmol) of crude 1-benzyl-3-benzylmethylaminomethyl-3-hydroxypyrrolidine in 50 ml of absolute tetrahydrofuran are added dropwise to 4 g of 80% strength sodium hydride in 100 ml of absolute tetrahydrofuran and the mixture is heated under reflux during this. After completion of hydrogen evolution, 12.4 g (87 mmol) of methyl iodide are slowly added dropwise and the mixture is subsequently heated overnight under reflux. The product is poured into ice water and extracted using toluene, the extract is dried over K2CO3 and concentrated, and the residue is distilled.
