Reaction Steps

(S)-2-Methylpropane-2-sulfinamide (110 mg, 0.908 mmol), (4-fluorophenyl)(2-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrrolo[2,1-f][1,2,4]triazin-4-yl)piperazin-1-yl)pyrimidin-5-yl)methanone (158 mg, 0.327 mmol) and ethyl orthotitanate (0.15 mL, 0.715 mmol) were stirred in THF (3.2 mL) at 70° C. for 18 hours. Room temperature was attained, water was added, and the products extracted into EtOAc (×2). The combined organic extracts were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo while loading onto Celite. Purification of the residue by MPLC (0-10% MeOH-EtOAc) gave (S,Z)—N-((4-fluorophenyl)(2-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrrolo[2,1-f][1,2,4]triazin-4-yl)piperazin-1-yl)pyrimidin-5-yl)methylene)-2-methylpropane-2-sulfinamide (192 mg, 0.327 mmol, 100% yield) as an orange solid. MS (ES+) C29H31FN10OS requires: 586. found: 587 [M+H]+.
