Procedure

To a solution of methyl 2-morpholin-4-ylacetate (1.0 g, 6.28 mmol) in 1 mL of anhydrous ethanol was added anhydrous hydrazine (0.305 mL, 6.28 mmol). The solution was heated to reflux temperature overnight. The solvent was then removed under reduced pressure and the product was isolated as a solid in a quantitative yield and was used without further purification: 1H NMR (CDCl3) δ8.11 (br s, 1H), 3.87 (br s, 2H), 3.71 (t, 4H), 3.09 (s, 6H), 2.53 (t, 4H); ES-MS (m/z) 160 [M+H]+.
