実験手順
N-(4-(2-pyrimidinyl)phenyl)-2,2-dimethylpropanamide (1.41 g, 5.48 mmol) was boiled in 6 M hydrochloric acid (40 ml) for 2 h. The mixture was cooled and made strongly basic with NaOH (s) and extracted with CH2Cl2 (2×50 ml), dried (Na2SO4) and the solvent was removed in vacuo. Trituration with n-hexane gave 0.83 g (88%) of 4-(2-pyrimidinyl)aniline as a light-yellow powder. The product was further transformed by Method B and Method G (using cyclohexanecarboxaldehyde). M.p. 236-238° C.
