Procedure
A mixture of 1.5 g of 1-(2-chloropyrid-5-ylmethyl)-2-nitroimino-3-methyl-5-n-propyl-1,3,5-triazacyclohexane, 0.5 g of solid sodium hydrogen carbonate, 20 ml of methanol and 10 ml of water is stirred for 24 hours at 50° C. The reaction mixture is concentrated by evaporation and the residue purified on silica gel with dichloromethane/methanol 95:5 as the eluant. This yields the title compound with a melting point of 149-151° C. (compound 2.2).
