Versuchsvorschrift

To a stirred solution of tert-butyl (1-(5-chloro-4-hydroxypyrrolo[2,1-f][1,2,4]triazin-2-yl)cyclopropyl)carbamate (500 mg, 1.54 mmol) in acetonitrile (50 mL) was added BOP (1.02 g, 2.31 mmol), DBU (0.464 mL, 3.08 mmol) and the reaction mixture was stirred at RT for 1 h. Pyridin-2-ylmethanamine (166 mg, 1.54 mmol) was added to the reaction mixture and stirred for 12 h. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in ethyl acetate (100 mL) and washed water (2×30 mL). The organic layer was separated, dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by CombiFlash ISCO (REDISEP®, SiO2, 12 g, 10% MeOH/CHCl3) to give tert-butyl (1-(5-chloro-4-((pyridin-2-ylmethyl)amino)pyrrolo[2,1-f][1,2,4]triazin-2-yl)cyclopropyl)carbamate (320 mg, 50.1%) as a pale yellow solid. LCMS Condition B-16: retention time 1.06 min, [M+1]=415.2. 1H NMR (300 MHz, DMSO-d6) δ ppm 0.89-0.92 (m, 2H), 1.15-1.17 (m, 2H), 1.38 (s, 9H), 4.75 (d, J=5.7 Hz, 2H), 6.69 (d, J=2.7 Hz, 1H), 7.25-7.33 (m, 3H), 7.52-7.56 (m, 1H), 7.73-7.76 (m, 1H), 7.96-7.98 (m, 1H), 8.53 (d, J=5.2 Hz, 1H).
