실험 절차
5-Methyl-2-nitroimino-hexahydro-1,3,5-triazine (3.0 g) was dissolved in dimethylformamide/DMF (20 ml), followed by portionwise addition of sodium hydride (950 mg: oil free) thereto at a temperature in the range of from 0° to 5° C. After one hour stirring at 0° to 5° C. a solution of 2-chloro-5-chloromethyl-pyrimidine (3.1 g) in 20 ml of DMF was added dropwise to the solution, the temperature was kept constant, followed by a five hour stirring. The reaction mixture thus obtained was poured into iced water, subjected to extraction with methylene chloride a few times and then the extract was dried with anhydrous magnesium sulfate which was removed from the solvent. The thus obtained residue was purified by silica gel column chromatography (eluant: ethanol: chloroform=1: 20), to obtain the desired 1-(2-chloro-5-pyridylmethyl)-5-methyl-2-nitroimino-hexahydro-1,3,5-triazine (3.7 g) having a melting point in the range of from 160° to 161° C.
