Procedure

To a solution of N-[1-(4′-amino-4-biphenylyl)-2-(4-morpholinyl)ethyl]-2-(6,7-dichloro-3-oxo-2,3-dihydro-4H-1,4-benzoxazin-4-yl)-N-methylacetamide (68 mg, 0.12 mmol) in dichloromethane (2 mL) was added isocyanatoethane (36.5 mg, 0.51 mmol). Triethylamine (36 mg, 0.36 mmol) was added, and the resultant mixture was stirred at room temperature for 18 h. The mixture was concentrated under reduced pressure, and the residue was purified by Gilson preparative HPLC (Xterra Prep RP, 30×100 mm, 45 mL/min, A: acetonitrile with 0.1% TFA B: water with 0.1% TFA, A: 20 to 50% over 15 min, UV detection at 214 nm) to give 53.5 mg (70%) of the title compound as an off white solid. MS (ES) m/e 640.2 [M+H]+.
