Combine phenyl isocyanate (16.3 mg, 0.137 mmol), 6-(2-amino-ethoxy)-7-chloro-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (46 mg, 0.137 mmol) in DCM (1.5 mL) and stir at ambient temperature for 16 h. Concentrate in vacuo. Purify by reverse phase HPLC (10-95% of solvent B in 12.8 min, 25 mL/min; solvent A: water, 0.1% trifluoroacetic acid; solvent B: acetonitrile, 0.1% trifluoroacetic acid; column: YMC SH-341-5, S-5 μm, 12 nm, 100×20 mm) to give 7-chloro-6-[2-(3-phenyl-ureido)-ethoxy]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine.
