실험 절차

A mixed solution of 14.5 g (0.1 mol) of 2,4-diamino-6-chloro-1,3,5-triazine prepared in Reference Example 1, 140 mL of water, and 29.2 g (0.3 mol) of cyclohexylamine was warmed with stirring and allowed to react at a reflux temperature for 1 hour. Further, an aqueous solution of 12 g of sodium hydroxide in 40 mL of water was dropwise added thereto over 1 hour and the mixture was aged for 1 hour. To the reaction mixture thus obtained was added 200 mL of toluene, and the resulting mixture was cooled down to room temperature. The crystals obtained were collected by filtration, washed with 100 mL of toluene and then with 100 mL of water, followed by drying under reduced pressure to obtain 17.9 g (yield 86%) of the titled compound. Melting point: 151° C.
