実験手順
Part C: 2-Bromo-4-(1-methylethyl)aniline (0.26 g) and 2-chloro-4-methyl-6-(2-thienyl)pyrimidine (0.21 g) in ethylene glycol were heated at reflux for 24 hours. The reaction mixture was diluted with ethyl acetate, washed with aq. sodium hydroxide solution (10%, 3×100 mL) and the organic phase was dried. Solvent removal gave a crude brown oil, which was purified on silica gel using 20% ethyl acetate in hexanes (Rf 0.5) as eluent to provide N-(2-bromo-4-isopropylphenyl)-4-methyl-6-(2-thienyl)-2-pyrimidinamine (0.1 g) as a solid, mp 98-101° C. Mass spec (NH3 --CI/DDIP); 390 (M+H)+.
