Reaction Steps

In a heavy wall flask was placed 1-(ethylsulfonyl)-4-(tetrahydrofuran-2-ylmethyl)piperidine-4-carbonitrile (15, 2 g, 6.98 mmol) and 2N ammonia in methanol (50 ml). To this was added commercially available Raney nickel slurry in water (1.8 g, 20.94 mmol) and the solution agitated under hydrogen atmosphere (45 psi) at room temp for 12 hours. The catalyst was filtered off using celite and washed with MeOH (200 ml) and the combined organics concentrated in vacuo to give 1-[1-(ethylsulfonyl)-4-(tetrahydrofuran-2-ylmethyl)piperidin-4-yl]methanamine (16) as a clear semi-solid.
