Reaction Steps

The title compound is synthesized as described for 7-[2-(6-phenyl-3H-imidazo[4,5-b]pyridin-2-yl)-ethyl]-4,5,6,7-tetrahydro-3H-azepin-2-ylamine (compound 1) from 98 mg of 7-{2-[6-(4-methoxy-phenyl)-3H-imidazo[4,5-b]pyridin-2-yl]-ethyl}-azepane-2-thione (compound A3) and 6.0 ml of methanol containing ammonia (strength: 7.0 M) at 50° C. for 5 days. Purification by flash chromatography on LiChroprep-NH2® (eluent: ethanol) affords 23 mg of the title compound as an amorphous, colorless solid of m.p. 306° C. ESI-MS: 364.2 (MH+). TLC: Rf=0.50 (LiChroprep-NH2® HPTLC, methanol/water 10:1 parts by volume).
