Versuchsvorschrift

To a flask charged with N2 was added 1-{4-[4-amino-6-(methoxymethyl)-7-piperidin-4-ylpyrrolo[2,1-f][1,2,4]triazin-5-yl]-2-fluorophenyl}-3-[2-fluoro-5-(trifluoro-methyl)phenyl]urea (Example 149) (30 mg, 0.052 mmol, 1.0 eq) and 1,2-dichloroethane (2 mL). Tetrahydrofuran was added dropwise until the reaction mixture was a complete solution. The solution was cooled to 0° C. and methyl isocyanate (5.2 μl, 1 eq) is added. The reaction mixture was allowed to gradually warm to rt over 17 hours. The reaction was concentrated and the residue dissolved in EtOAc. The organic phase was washed with saturated sodium bicarbonate solution (2×), brine (1×), separated and the organic layer dried (Na2SO4). The organic layer was filtered, concentrated and purified via flash column chromatography (tetrahydrofuran). The purified fractions were collected, concentrated, stirred in hexanes and filtered. The filtrate was placed under vacuum overnight to yield the title compound (18 mg, 32.8% yield). 1H-NMR (DMSO-d6) δ 9.44 (s, 1H), 9.29 (s, 1H), 8.65 (d, J=7.2 Hz, 1H), 8.29 (t, J=8.4 Hz, 1H), 7.88 (s, 1H), 7.51 (t, J=9.9 Hz, 1H), 7.41 (m, 1H), 7.2 (dd, J=12.1, 1.9 Hz, 1H), 7.1 (dd, J=8.5, 1.4 Hz, 1H), 4.22 (s, 2H), 4.06 (m, 2H), 3.42 (m, 1H), 3.15 (s, 3H), 2.73 (t, J=12.4 Hz, 2H), 2.57 (d, J=4.3 Hz, 3H) 2.17 (m, 2H), 1.59 (m, 2H); MS [M+H]+=633; LCMS RT=2.97 min.
