Procedure

To a solution of 2-(4-ethoxy-2-oxo-2,3-dihydro-benzo[b][1,4]diazepin-1-yl)-N-isopropyl-N-phenyl-acetamide (Preparation 5(B) (177 mg, 0.466 mmol) in glacial acetic acid (4 mL) was added 3-hydroxy benzohydrazide (90 mg, 0.591 mmol). The reaction was heated to 120° C. for 3 hours, was cooled to room temperature, and was concentrated in vacuo. The residue was triturated with 50% Et2O in hexanes and the solids were filtered. The solids were dissolved in CH2Cl2 and the organic solution was washed with aqueous NaHCO3, dried (MgSO4) and concentrated to provide 244 mg of 2-[1-(3-hydroxy-phenyl)-5-oxo-4,5-dihydro-2,3,6,10b-tetraaza-benzo[e]azulen-6-yl]-N-isopropyl-N-phenyl-acetamide. 1H NMR (CD3OD) δ 7.74 (s, 2H), 7.56-7.18 (m, 10H), 6.91 (m, 1H), 4.86 (m, 1H), 4.30-4.10 (m, 2H), 3.98 (d, 1H), 3.71 (d, 1H), 1.06 (m, 6H).
