Procedure
A mixture of 4-(1,4-diaza-bicyclo[3.2.2]non-4-yl)-phenylamine (0.43 g, 2.0 mmol), phenylisocyanate (0.29 ml, 2.5 mmol) and methanol (60 ml) was stirred at room temperature for hours. The mixture was evaporated and diethylether (30 ml) was added, the precipitate was filtered. The product was isolated. Yield 0.23 g (34%). Mp. 145° C. (dec).
