Procedure
A solution of 460 mg (1.21 mmol) of (2-benzylamino-5-propargyloxyphenyl)-(4-cyclopropyl-phenyl)-methanone (step E) and 118 mg (1.81 mmol) sodium cyanate in 20 ml glacial acetic acid is stirred at rt for 8 h. Then the mixture is diluted with water and ethyl acetate. The layers are separated and the organic phase is washed with water and bicarbonate solution. Chromatography (dichloromethane/MeOH) of the crude product affords a yellow foam. m.p. 112-113° C.
