実験手順

The product of step (b) (2.22 g, 0.00948 moles) was dissolved in 15 ml chlorobenzene. N,N-diethylaniline hydrobromide (2.18 g, 0.00948 moles) was added followed by 1-pyrrolidinecarbonitrile (1.37 g, 0.01422 moles). A catalytic amount of 4-dimethylaminopyridine was added and the reaction heated to reflux for 6 hours. The reaction was then cooled to room temperature and diluted with 100 ml ethyl acetate. A sticky oil precipitated from solution and was stirred for 24 hours. The resulting solids were filtered and recrystallized from hot isopropanol to give the N-(4(2-((4-morpholinyl)carbonyl)ethyl)phenyl)-1-pyrrolidinecarboximidamide hydrobromide, M.P. 207-209° C.
