Lithium aluminium hydride (1 m in THF, 10 ml, 10 mmol) was added to a solution of the amide from Step 1 (1.0 g, 4.6 mmol) in THF (20 ml) and the mixture was heated at reflux for 16 hours. The reaction was cooled in ice and treated successively with water (0.4 ml), sodium hydroxide (0.4 ml) and water (1.2 ml) allowing 10 minutes between additions. The mixture was filtered through a bed of Celite® and washed through with THF. The filtrate was evaporated in vacuo to provide 7-(N-benzylamino)hept-1-yne as a yellow oil (924 mg, 99%). (ES+) 202 ([MH]+).
