The stability of these compounds as well as of the anils and toludile derived from cotarnornethyl phenyl urea is in striking contrast with the instability of the corresponding derivatives of cotarnine itself and the difference should obviously be attributed to the presence of the. [...] The presence of the secondary imino-hydrogen in cotarnine and its absence in benzoylSTUDIES IN TICE COTARNINE SERIES 423 cotarnine and cotarnomethylphenylurea would thus account for the remarkable difference in the reactivity of the aldehydic group which is present in both these compounds. [...] In view of the proximity of the nitrand the aldehyde groups in the molecule of this compoud it was considered possible that the reduction of the nitro group would lead to the syntheses of interesting compounds and the subject is still under investigation. [...] It is very probable that condensations of the latter type occur only with the carbinol form of cotarnine the unreactivity of benzoyl cotarnine being explained by the impossibility of the formation of the carbinol phase in the latter. [...] The view that the change of the aldehyde into the carbinol phase has been effected by the solvent is strikingly supported by the observation that the unsaturated compound (I) m.p.
