Versuchsvorschrift

A mixture of 4-(1-(4-methoxybenzyl)-3-iodo-1H-pyrazolo[3,4-b]pyridin-4-yloxy)-3-fluorobenzenamine (0.123 g, 0.25 mmol, prepared according to Example 7, Step B), ±(3S*,4R*)-tert-butyl 4-amino-3-fluoropiperidine-1-carboxylate (0.164 g, 0.750 mmol, prepared according to WO 2006/087543), copper(I)iodide (0.00952 g, 0.0500 mmol), (S)-pyrrolidine-2-carboxylic acid (0.0115 g, 0.100 mmol), K2CO3 (0.173 g, 1.25 mmol), and DMSO (1 mL) was stirred at 100° C. for 3 days. The reaction was partitioned between EtOAc and water. The phases were separated and the aqueous phase was re-extracted with EtOAc (5 mL). The combined organic phases were washed with water, dried (Na2SO4), filtered, and concentrated. The crude was purified by preparative TLC (1 mm thickness, Rf=0.56) eluting with 10% MeOH/CHCl3. LRMS (APCI+): m/z 581 (M+1) detected.
