[0249] Reference Example 1. Preparation method of trifrofluoromethylpyrimidine-1-lysonium-1,6-diamine 2,4,6-trimethylsulfonate
[0250] [Chemical Formula 9]
[0251]
[0252]2,2,2-trifluoroacetic acid (4.4 g, 2.54 mmol, 2.9 mL) was added to a microwave tube having a magnetic stirrer, and then added (tert-butoxycarbonyl amino) 2, 4, 6- at 0 ° C. Trimethylbenzenesulfonate (1 g, 2.54 mmol). The reaction mixture was stirred at 0 ° C for 2 hours, and ice water was added, and the precipitate was recovered by filtration. Wash the moist filter cake with water, and dissolved in dichloromethane (5 mL), dried to sodium sulfate. The resulting solution was added dropwise to 6-trifluoromethylpyrimidine-4-amine (0.373 g, dichloromethane (5ml) (5ml) (5 ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5 ml) (5 ml) (5 ml) (5 ml) (5 ml) (5 ml) (5 ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml) (5ml). )middle. After 1 hour after this temperature and after one night at room...

[0253] Reference Example 2.2- (3-ethylsulfonyl-5-bromo-2-pyridyl) -7-trifluoromethyl-[1,2,4] triazole [1,5-C] pyrimidine preparation method
[0254] [Chemical Formula 10]
[0255]
[0256] 4-trifluoroamine-1-lyson-1,6-diamine 2,4,6-trimethylsulfonate (0.3 g, 0.791 mmol), 3-ethylsulfonyl-5-bromine Pyridin-2-carboxylic acid (0.284 g, 1.18 mmol) and 3- (ethylene aminomethylene) -N, N-dimethyl-propane-1-amine hydrochloride (0.18 g, 0.94 mmol) Dissolved in pyridine (2 mL), heated at 120 ° C for 3 hours. Then, the reaction mixture was injected into water, and the aqueous layer was extracted 3 times using EtOAc (ethyl acetate). Wash the combined organic layers in times of water and brine, use anhydrous NA 2 SO 4 (Sodium sulfate) was dried and filtered and concentrated under reduced pressure. The crude product was washed with diethyl ether and filtered to give a target product as a white powder (90 mg, 33%).
