Reaction Steps

A solution of 1-nitroso-5-fluoro-1′-[trans-3-(4-chlorophenyl)allyl]spiro[indoline-3,4′-piperidine] (5 g) in tetrahydrofuran (60 ml) was added dropwise to a suspension of lithium aluminium hydride (1.47 g) in tetrahydrofuran (60 ml) at 0° C. and the resulting mixture was stirred at room temperature for 2.5 hours. Water (4.8 ml) was carefully added, followed by 15% aqueous sodium hydroxide (4.8 ml), and finally water (14.4 ml). The mixture was stirred for 0.5 hours, diluted with ethyl acetate, dried over sodium sulfate, and filtered. The solvents were evaporated in vacuo to afford 5.1 g (100%) of the desired amino-indoline as a solid. MS (ES+) 372.
