Reaction Steps

A mixture of (1S)-3-(3,6-Dihydropyrazolo[4,3-d]pyrrolo[2,3-b]pyridin-1-yl)cyclopentanamine (0.20 g, 0.83 mmol, Preparation #30), 6-chloronicotinonitrile (0.12 g, 0.83 mmol), DIEA (0.22 mL, 1.2 mmol), and EtOH (3 mL) were heated for about 1 h at about 120° C. in a microwave (250 psi maximum pressure, 1 min ramp, 300 max watts). The reaction mixture was concentrated in vacuo and purified by RP-HPLC (Table 2, Method s) to give 6-((1S,3S)-3-(3,6-dihydropyrazolo[4,3-d]pyrrolo[2,3-b]pyridin-1-yl)cyclopentylamino)nicotinonitrile (0.014 g, 5%): LC/MS (Table 2, Method a) Rt=1.75 min; m/z: 344 (M+H)+ and 6-((1S,3R)-3-(3,6-dihydropyrazolo[4,3-d]pyrrolo[2,3-b]pyridin-1-yl)cyclopentylamino)nicotinonitrile (0.020 g, 7%): LC/MS (Table 2, Method a) Rt=1.81 min; m/z: 344 (M+H)+.
