Procedure

To a stirred slurry of lithium aluminium hydride (5.70 g) in dry tetrahydrofuran (100 ml) was added β-carbethoxymethyl-caprolactam (10.3 g) in dry tetrahydrofuran (150 ml) over a period of 30 minutes. The mixture was refluxed for 2.5 hours, cooled and treated very slowly with water. The precipitate was filtered off and the filtrate was evaporated to yield the title compound as a viscous oil, which was used in the next step without purification.
