Reaction Steps

To a solution of compound 39.3 in dichloromethane under nitrogen was added 3-trifluoromethylphenyl isocyanate dropwise. After about 0.1 hour, a white precipitate formed. The precipitate was filtered off, washed with dichloromethane and dried under high-vacuum to yield 485 mg (75%) of (2-{4-[3-(3-trifluoromethyl-phenyl)-ureido]-imidazol-1-yl}ethyl)-carbamic acid tert-butyl ester (compound 39.4) as a white solid, ES (+) MS m/e=414 (M+H+).
