Procedure

5-Bromo-3-pyridylcarbonylazide (3.7 g, 16 mmoles) was heated under reflux in dry toluene (100 ml) for 1 hr. After cooling the resulting solution of isocyanate was treated with a solution of 5-methoxy-6-trifluoromethyl indoline (D11) (3.5 g, 16 mmoles) in dichloromethane (600 ml) and stirred overnight. The mixture was concentrated in vacuo and the residue triturated with diethyl ether. Filtration and washing with more diethyl ether gave the title compound (D26) (5.4 g, 81%).
