Versuchsvorschrift

Triethylamine (0.013 mL, 0.093 mmol) was added to a solution of phenyl (3-(tert-butyl)-1-(p-tolyl)-1H-pyrazol-5-yl)carbamate (Intermediate B) (0.042 g, 0.121 mmol) and N-(4-(((4-aminonaphthalen-1-yl)oxy)methyl)pyridin-2-yl)-6-ethylpyrazin-2-amine (Intermediate D) (0.093 g, 0.250 mmol) in THF (1.5 mL) at 40° C. The reaction mixture was stirred at 40° C. for 40 min then cooled to RT and stirred for 3 days, and then concentrated in vacuo. The crude product was purified by silica gel chromatography (12 g column, 0 to 5% MeOH in DCM) to give an off white-brown solid. The product was re-purified by preparative HPLC (Gilson, Acidic (0.1% Formic acid), Acidic, Waters X-Select Prep-C18, 5 μm, 19×50 mm column, 45-75% MeCN in Water) to afford the title compound 1-(3-(tert-butyl)-1-(p-tolyl)-1H-pyrazol-5-yl)-3-(4-((2-((6-ethylpyrazin-2-yl)amino)pyridin-4-yl)methoxy)naphthalen-1-yl)urea as an off white solid (0.029 g, 49%); Rt 2.26 min (Method 1); m/z 627 (M+H)+ (ES+), 625 (M−H)− (ES−); 1H NMR δ: 1.18 (3H, t), 1.28 (9H, s), 2.40 (3H, s), 2.63 (2H, q), 5.36 (2H, s), 6.36 (1H, s), 7.02 (1H, d), 7.07 (1H, dd), 7.37 (2H, m), 7.45 (2H, m), 7.56-7.67 (3H, overlapping m), 7.94 (1H, m), 7.99 (1H, s), 8.02 (1H, s), 8.30 (1H, d), 8.39 (1H, m), 8.60 (1H, s), 8.81 (1H, s), 8.92 (1H, s), 10.08 (1H, s).
