Trimethylsilyl cyanide (8.5 g) was added to a stirred mixture of 2-fluorobenzaldehyde (10.6 g) and zinc iodide (500 mg) in dry ether (150 ml). The mixture was stirred at ambient temperature for 24 hours and was then added dropwise to a stirred suspension of lithium aluminium hydride (3.2 g) in dry ether (50 ml) under nitrogen. The mixture was refluxed for 2 hours, cooled and water (3.2 ml), 2 N sodium hydroxide solution (3.2 ml) and water (9.6 ml) slowly added. The precipitate was filtered off, the filtrate was dried (MgSO4) and evaporated to a yellow oil (13.0 g) which crystallised slowly on standing.
