Versuchsvorschrift

To a solution of 3-(1,1-dimethylethyl)-6-fluoro-1-methyl-9-(methyloxy)-5-{3-methyl-4-[(phenylmethyl)oxy]phenyl}-3H-pyrazolo[3,4-c]isoquinolin-8-ol (207 mg, 0.42 mmol) in DMF (2 mL) was added cesium carbonate (274 mg, 0.84 mmol) and tert-butyl 4-{[(methylsulfonyl)oxy]methyl}piperidine-1-carboxylate (135 mg, 0.46 mmol). The mixture was heated to 90° C. and stirred for 1.5 h. After cooling to rt, water was added and the resulting aqueous mixture was extracted twice with ethyl acetate. The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude residue was purified by flash chromatography (gradient: 25% ethyl acetate in hexanes to 30% ethyl acetate in hexanes) to provide 1,1-dimethylethyl 4-{[(3-(1,1-dimethylethyl)-6-fluoro-1-methyl-9-(methyloxy)-5-{3-methyl-4-[(phenylmethyl)oxy]phenyl}-3H-pyrazolo[3,4-c]isoquinolin-8-yl)oxy]methyl}piperidine-1-carboxylate (214 mg, 0.31 mmol, 73% yield) as a yellow oil. 1H NMR (400 MHz, CDCl3): δ 7.51-7.34 (m, 7H), 6.98 (d, 1H), 6.83 (d, 1H), 5.16 (s, 2H), 4.22 (br m, 2H), 3.98 (d, 2H), 3.91 (s, 3H), 2.89 (s, 3H), 2.80 (br m, 2H), 2.37 (s, 3H), 2.12 (m, 1H), 1.93-1.88 (m, 2H), 1.85 (s, 9H), 1.48 (s, 9H), 1.39-1.35 (m, 2H); MS (I) for C41H49FN4O5: 697 (MH+).
