Versuchsvorschrift

A mixture of trans-3-(4-amino-5-iodopyrrolo[2,3-d]pyrimidin-7-yl)-cyclobutanecarboxylic acid amide (119 mg, 0.333 mmol), 2-phenyl-7-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-quinoline (133 mg, 0.402 mmol), Na2CO3 (88.3 mg, 0.833 mmol), Pd(PPh3)4 (23.1 mg, 0.0200 mmol), DMF (5 mL), and water (1 mL) was purged with nitrogen for 30 min and heated to 80° C. for 22 h. To the cooled reaction solution was added water (10 mL), the mixture was extracted with EtOAc (3×15 mL), the combined organic layers were washed with water (2×10 mL) and brine, dried over MgSO4, filtered, and concentrated. The residue was triturated with MeOH to give the title compound as light yellow solid. Chromatography of the mother liquor on silica gel (8 g, eluting with 2%→4%→6%→8%→10% MeOH in CH2Cl2) gave an additional batch. Both batches contained a small amount of the corresponding cis isomer (see below for its independent synthesis). 1H NMR (CDCl3, 400 MHz): δ=2.70-2.78 (m, 2 H), 2.97-3.08 (m, 2 H), 3.21-3.26 (m, 1 H), 5.66-5.72 (quintet, 1 H, J=8.4 Hz), 6.54 (brs, 2 H), 7.08 (s, 1 H), 7.59 (s, 1 H), 7.68-7.78 (m, 3 H), 7.94-7.98 (m, 1 H), 8.12 (s, 1 H), 8.26-8.28 (d, 1 H, J=8.4 Hz), 8.32-8.37 (m, 3 H), 8.48-8.53 (m, 2 H), 8.66-8.68 (d, 1 H, J=8.8 Hz). MS (ES+): 435.2 [MH+]. HPLC: tR=2.3 min (polar—5 min).
