Versuchsvorschrift

1-[4-(4-Chloro-3-methoxy-phenyl)-piperazin-1-yl]-2-(3-iodo-pyrazolo[3,4-b]pyridin-1-yl)-ethanone (128 Mg) and CuCN (112 Mg) were combined in N-methylpyridone (NMP) (1 mL) and heated at 165° C. for 16 hr, then cooled to room temperature. The reaction mixture was purified on preparative HPLC to afford 1-{2-[4-(4-Chloro-3-methoxy-phenyl)-piperazin-1-yl]-2-oxo-ethyl}-1H-pyrazolo[3,4-b]pyridine-3-carbonitrile as a white powder: LCMS (ES) M+H411.5, Rf 2.33 min (Agilent Zorbax SB-C18, 2.1×50 Mm, 5μ, 35° C., 1 mL/min flow rate, a 2.5 min gradient of 20% to 100% B with a 1.1 min wash at 100% B; A=0.1% formic acid/5% acetonitrile/94.9% water, B=0.1% formic acid/5% water/94.9% acetonitrile).
