## Abstract The adduct compound was prepared by condensation of equimolar quantities of analar vaniline and 1βphenylβ2βamino pyrimidine in absolute ethyl alcohol. Prismatic crystals were obtained with the crystallographic data: __a__ = 12.901 (6), __b__ = 19.297 (9), __c__ = 6.828 (3) Γ , Ξ³ = 102.67
Seven crystalline N'-alkyl-N2-arylthioureas were studied by I3C CP/MAS NMR and by IR spectroscopy. The double set of signals in I3C CP/MAS spectra indicates that molecules of N'-ethyl-Nz-(3-methy1phenyl)thiourea and N'-ethyl-N2-(4-methyIphenyl)thiourea are crystallographically non-equivalent. N'-Pro
