Procedure

A solution of N-(cyclopropylmethyl)-5-(3-formyl-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)nicotinamide (XXXI) (0.404 g, 1.0 mmol), 3,3′-bipyridine-4,5-diamine (XV) (186 mg, 1.0 mmol) and sulfur (35 mg, 1.1 mmol) in dry DMF (10 mL) was heated at 140° C. overnight. The reaction was cooled and evaporated under vacuum. The residue was suspended in water, sonicated and filtered. The solid was washed with cold water and dried under vacuum. The crude product was dissolved in DCM and cooled to 4oC overnight to get N-(cyclopropylmethyl)-5-(3-(7-(pyridin-3-yl)-3H-imidazo[4,5-c]pyridin-2-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)nicotinamide (XXXII) as a brown solid (130 mg, 0.23 mmol, 23% yield). 1H NMR (DMSO-d6) δ ppm 0.19-0.37 (m, 2H), 0.36-0.58 (m, 2H), 0.97-1.115 (m, 1H), 1.67 (br, 2H), 2.14 (d, J=9.98 Hz, 2H), 2.40-2.46 (m, 1H), 3.20-3.33 (m, 3H), 3.75-4.14 (m, 2H), 6.13 (d, J=8.29 Hz, 1H), 7.60 (dd, J=7.82, 4.80 Hz, 1H), 7.92-8.12 (m, 3H), 8.20 (d, J=8.67 Hz, 1H), 8.55-8.67 (m, 2H), 8.94 (br s, 3H), 9.06 (d, J=1.88 Hz, 1H), 9.19 (d, J=1.87 Hz, 1H); ESIMS found C33H30N8O2 m/z 571 (M+H).
