7-(3-Isopropoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazin-2-ol (100 mg, 0.4 mmol), N-Phenylbis(trifluoromethanesulphonimide) (146 mg, 0.408 mmol), N,N-Diisopropylethylamine (0.194 mL, 1.11 mmol), and N,N-Dimethylformamide (3 mL, 40 mmol) and stir at room temperature for half an hour. Add 2-[4-(4-Amino-phenyl)-piperidin-1-yl]-acetamide (139 mg, 0.594 mmol) and stir at 60° C. overnight. The reaction was concentrated, DMSO added, filtered and placed onto the Gilson for purification. The most pure fractions were basified with saturated sodium bicarbonate, extracted with ethyl acetate, dried, filtered and collected as a yellow solid (47 mg, 30%). MP 233-235° C. LCMS (E/I+) 485 (M+H).
