Reaction Steps

To a solution of the above (4-chloro-5-trifluoromethyl-pyrimidin-2-yl)-(2-trifluoromethoxy-benzyl)-amine (80 mg, 0.22 mmol) in DMF (2 mL) was added the Boc-protected cyclohexyl amine (74 mg, 0.33 mmol) followed by DIPEA (37 μL, 0.22 mmol). The reaction mixture was stirred at 70° C. for 3 h. When the reaction was complete, the reaction mixture was diluted with EtOAc and washed with water (×4). The organic phase was dried over anhydrous Na2SO4 and concentrated in vacuo. The resulting residue was purified by silica gel preparative TLC using 95:5 CH2Cl2:MeOH as an eluent. The resulting residue was then re-dissolved in CH2Cl2 (10 mL) and TFA (1 mL) was added. The reaction mixture was stirred at room temperature for 2 h and treated with saturated NaHCO3. The product was extracted with CH2Cl2 and dried over anhydrous Na2SO4. Silica gel preparative TLC using CH2Cl2:MeOH:NH4OH 10:1:0.2 as an eluent afforded 56 mg (56%) of the title compound as a white solid, m/z 462.4 [M−1]+.
