Versuchsvorschrift

To a stirred solution of 1-(benzo[d]oxazol-2-yl)cyclopropanecarboxylic acid (3.8 mg, 0.019 mmol) in 150 μL dichloromethane at room temperature under nitrogen was added DIEA (8 μL, 0.047 mmol) followed by EDCI (4.5 mg, 0.024 mmol) and HOBT-H2O (3.6 mg, 0.024 mmol). After 15 minutes, a solution of 1-(1-(4-methoxybenzyl)-4-(4-amino-2-fluorophenoxy)-1H-pyrazolo[3,4-b]pyridin-3-yl)-N,N-dimethylpiperidin-4-amine (7.7 mg, 0.016 mmol) (prepared in Example 93, Step A) in 150 μL dichloromethane was added. After stirring for 48 hours, the reaction was diluted to 30 mL with dichloromethane and washed with 10% sodium carbonate solution. The organics were dried (MgSO4), filtered and concentrated. The crude product was loaded onto a Biotage 12S column with dichloromethane and eluted with a step gradient of dichloromethane (100 mL), 2.5/97.5 MeOH/dichloromethane (100 mL) and 5/95 MeOH/dichloromethane to provide the desired product as a white foam (6.6 mg, 62% yield).
