Reaction Steps

A suspension of methyl [1-benzyl-3-(nitromethyl)pyrrolidin-3-yl]acetate a46 (3.3 g, 1.1 mmol, 1 eq) and Raney nickel (1 g of a 50% slurry in water) in ethanol (200 ml) is shaken in a Parr bottle at 30° C. for 24 h, under a hydrogen pressure of 40 psi. The reaction mixture is then filtered through Celite and the filtrate is concentrated to afford 1.8 g of 7-benzyl-2,7-diazaspiro[4.4]nonan-3-one a47 as a brown oil.
