Reaction Conditions:
with tetrabutylammomium bromide;sodium hydroxide in water at 100; for 8 h;Inert atmosphere;
Steps:
General procedure for intermediate F.
2,3,5,6-Tetrachloropyridine (0.1 mol), NaOH, TBAB and 60mL H2O were added to a 100 mL eggplant-shaped. The mixture was heated at 100 °C for 8 hours, and monitored by TLC. Upon the reaction completion, the mixture was poured into icewater (100 mL) and was acidified to pH = 5-6. After filtration and extraction, F was obtained as white solid. The analytical data corresponded to the literature [15, 16].
