Phenetyl urea

While the preparation of phenylurea itself by the foregoing process does not appear in the older literature, an analogous process has been patented for the preparation of -phenetyl-urea,fi in which />-phenetidine is heated with urea nitrate (or -phenetidine hydrochloride with urea) in aqueous solution. This reaction appears to be generally applicable to aromatic primary amines it does not, however, appear to be so well suited to the preparation of the corresponding derivatives of secondary amines.
