Participants

Conditions

Temperature: 150 °C

Procedure

To 4-chloro-6-(2-methoxypyridin-4-yl)-1-methyl-1H-pyrazolo[3,4-b]pyridine (0.4 g) and 4-(methylsulfonyl)phenol (0.5 g) was added DMF (3.4 mL) and potassium carbonate (1.0 g). Nitrogen was bubbled through the solution for 5 min. The reaction mixture was heated in a microwave reactor for 1 h at 150° C., then purified by reverse phase HPLC to provide 118 (0.3 g). MS (ESI) m/z 411.1 (M+1)+
