実験手順
a)To a stirred solution of 6 g of diphenyl cyanocarbonimidate in 50 ml of dichloromethane at room temperature were added portionwise 2.1 g of piperidine. Stirring was continued for 30 minutes at room temperature. The reaction mixture was evaporated and the residue was crystallized from 2,2'-oxybispropane. The crystals were filtered off and dried, yielding 4.6 g (80.7%) of [phenoxy(1-piperidinyl)methylene]cyanamide; mp. 85.7° C. (interm. 32).
