Procedure

A solution of 1-{3-[2-methyl-4-(3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulene-9-carbonyl)-phenyl]-propionyl}-piperidine-4-carbaldehyde from Example E58.1 (2.43 mg, 0.005 mmol) in 1,2-dichloroethane (0.05 ml) was added to a solution of butyl-methyl-amine (0.43 mg, 0.005 mmol) in 1,2-dichloroethane (0.05 ml) and the mixture was heated at 50° C. for 3 h then stirred at room temperature for 2 days. A solution of sodium tri-acetoxyborohydride (1.59 mg, 0.0075 mmol) in DMF (0.05 ml) was added and the mixture was stirred for 20 h at room temperature. Solvents were removed in vacuo to yield the title compound. MS: (ESI)+:[M+H]+=557.6
