Procedure

To a solution of N-[1-(3′-amino-4-biphenylyl)-2-(4-morpholinyl)ethyl]-2-(6,7-dichloro-3-oxo-2,3-dihydro-4H-1,4-benzoxazin-4-yl)-N-methylacetamide (52 mg, 0.6 mmol) in dichloromethane (1 mL) was added isopropylisocyanate (36.5 mg, 0.51 mmol). Triethylamine (60 mg, 0.60 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 (Sunfire Prep C18, 30×150 mm, 50 mL/min, A: acetonitrile with 0.1% TFA B: water with 0.1% TFA, A: 30 to 60% over 12 min, UV detection at 214 nm) to give 40.8 mg (52%) of the title compound as off white solid. MS (ES) m/e 654.3 [M+H]+.
