Reaction Steps

A mixture of 1-(piperidin-3-yl)-3,6-dihydropyrazolo[4,3-d]pyrrolo[2,3-b]pyridine (0.16 g, 0.65 mmol, Example #26, Step E) and 6-chloronicotinonitrile (0.090 g, 0.65 mmol) with DIEA (0.37 mL, 2.12 mmol) in EtOH (3 mL) was heated at about 120° C. for about 15 min in a microwave reactor. The crude material was purified by RP-HPLC (Table 2, Method h) to give 6-(3-(3,6-dihydropyrazolo[4,3-d]pyrrolo[2,3-b]pyridin-1-yl)piperidin-1-yl)nicotinonitrile (0.012 g, 6%): LC/MS (Table 2, Method a) Rt=1.96 min; m/z: 344 (M+H)+.
