A mixed solution of 14.5 g (0.1 mol) of 2,4-diamino-6-chloro-1,3,5-triazine which is an intermediate product synthesized in the Reference Example 1, 140 mL of water, and 29.2 g (0.3 mol) of cyclohexylamine was heated while stirring, followed by being reated for 1 hour at reflux temperature. Subsequently, the reaction mixture was added with 40 mL of aqueous solution containing 12 g of sodium hydroxide over 1 hour, followed by aging for 1 hour. Into a reaction mixture obtained, 200 mL of toluene was added, followed by being cooled to room temperature. A crystalline obtained was filtered, followed by washing in order with 100 mL of toluene, and then 100 mL of water, and drying at reduced pressure to obtain 17.9 g (a yield of 86%) of the above-identified compound. Melting point: 151° C.
