The reaction was allowed to warm to room temperature and stirred 2 hours. The reaction was quenched with water, extracted with dichloromethane and the combined organics dried over sodium sulfate. The organic phase was concentrated under reduced pressure to provide 5-(tert-butyldimethylsilyloxymethyl)-5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinoline. This material was treated essentially as described in Preparation II to provide the title compounds.
