To a solution of 2-chloro-4-(4-((4-(trifluoromethoxy)benzyl)oxy)piperidin-1-yl)-1,3,5-triazine (500 mg, 1.28 mmol) in isopropanol (4 mL, 3 mL/mmol) was added DIPEA (0.4 mL, 1.92 mmol) and 3-amino-N,2-dimethylbenzamide (211 mg, 1.29 mmol) and the reaction was stirred at 80° C. for 24 h. The reaction mixture was concentrated under reduced pressure and extracted with EtOAc (2×30 ml). The organic extracts were washed with brine, dried over sodium sulfate and concentrated under reduced pressure. Purification by silica gel column chromatography provided N,2-dimethyl-3-((4-(4-((4-(trifluoromethoxy)benzyl)oxy)piperidin-1-yl)-1,3,5-triazin-2-yl)amino)benzamide (100 mg, 16%) as a solid. Observed mass (M+1): 517.1.
