Procedure

4-[(Cyclopropyl-{3-[2-methyl-4-(3-methyl-4,10-dihydro-3H-2,3,4,9-tetraaza-benzo[f]azulene-9-carbonyl)-phenyl]-propionyl}-amino)-methyl]-piperidine-1-carboxylic acid tert-butyl ester from Example E87.1 (235 mg, 0.37 mmol) was dissolved in 4M HCl solution in dioxan (5 ml). The mixture was stirred for 1 h at room temperature, concentrated in vacuo and azeotroped with toluene. The residue was dissolved in 1M HCl, washed twice with dichloromethane and freeze-dried to give an off-white solid identified as the title compound (82 mg, 39%).
