Reaction Steps

Pyrimidin-4-amine (0.337 mmol, 0.032 g) and N-ethyl-N-isopropylpropan-2-amine (1.145 mmol, 0.189 mL, 0.148 g) were stirred in dichloromethane (2 mL) at room temperature. Triphosgene (0.125 mmol, 0.037 g) was added and the reaction stirred for 30 minutes. (4-Amino-3-fluorophenyl)(4-(4-(2-(tert-butyldimethylsilyloxy)-1,1,1,3,3,3-hexafluoropropan-2-yl)benzyl)piperazin-1-yl)methanone (0.168 mmol, 0.1 g) was added and the reaction heated to 120° C. in the microwave for 10 minutes. The reaction mixture was washed with water and concentrated under reduced pressure. The resulting residue was purified by silica column chromatography (eluant dichloromethane/methanol 0% to 5%) to afford the title compound (63 mg). MS (ESI) m/z 715.7 [M+H]+
