Procedure

To a mixture of O-methyl-N-nitroisourea (1.25 g, 10.53 mmol), water (20 ml) and concentrated hydrochloric acid (0.85 ml, 10.03 mmol) was added 5-(aminomethyl)-2-chloropyridine (1.43 g, 10.03 mmol) dropwise over 5 minutes at room temperature with stirring. The reaction mixture was neutralized with 40% aqueous sodium hydroxide solution and adjusted to pH 7.2. After 17 hours of stirring at room temperature, the resulting crystals were collected. The crystals were washed with water and dried. As a result, 1.16 g (47.3% yield) of O-methyl-N-(6-chloro-3-pyridylmethyl)-N'-nitroisourea was obtained as white crystals. M.p. 112-113° C.
