Procedure

The resolved aminobenzodiazepine of Example 26 (980 mg, 2.8 mmol) in toluene (10 ml) was treated with the isocyanate prepared from the acid of Example 56B (985 mg, 5.5 mmol) following the method of Example 38. The product was purified by flash chromatography on silica gel (eluant EtOAc:hexane fr 75:25 v/v) to provide the title compound (960 mg, 65%).
