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 100 mg of N-(2-fluoro-4-methyl-phenyl)-4-{2-[2-(7-thioxo-azepan-2-yl)-ethyl]-3H-imidazo[4,5-b]pyridin-6-yl}-benzenesulfonamide (compound A8) and 4.30 ml of methanol containing ammonia (strength: 7.0 M) at 50° C. for 90 hours. Subsequently, the mixture is filtered with suction. The residue is washed with 20 ml of methanol and dried under high vacuum to afford 61 mg of the pure title compound as an amorphous, colorless solid of m.p. 265° C. ESI-MS: 521.2 (MH+), TLC: Rf=0.28 (HPTLC RP-C18; acetonitrile/water 2:1 parts by volume).
