Procedure

A solution of acyl azide D15) (370 mg, 1.6 mmol) in toluene (5 ml) was heated to reflux for 0.25 h. After cooling to room temperature, the solution of the isocyanate was added to a solution of 5-methoxy-6-trifluoromethyl indoline (0.35 g, 1.6 mmol) in dichloromethane (10 ml). Filtration and drying afforded the title compound as a white solid (100 mg, 15%), m.p.>200° C.
