Procedure

To a solution of methyl 2-fluoromethyl-2,5-diaminopentanoate dihydrochloride (2.5 g) in methanol (30 ml) is added under nitrogen a solution of sodium methylate (prepared from 0.46 g of sodium) in methanol (20 ml). The reaction mixture is stirred for 1 hour at room temperature and then concentrated in vacuo. The residue is taken up in CH2Cl2. The insoluble material is removed by filtration, and the filtrate is concentrated to give 1 g of 3-amino-3-fluoromethyl-2-piperidone: m.p. 132° C. (from CH2CL2 /pentane).
